"The woman is created for a man, not a man for a woman" - such a postulate ...
For experienced electrical installations more than workthan a banal setting of the switch. In fact, there is nothing superpower in this operation. True, in addition to the mandatory compliance with the rules marked in the Code for electricians Pue, it is still necessary to know some subtleties. They will prompt beginners how to connect the light switch in your favorite bathhouse so that bath procedures take place in civilized conditions.
Competent selection of "Captain" wiring
The rank of general will leave yourself, because It is necessary to serve the switch under our beginning. Colonel Assign an old sample packet switch or a new two-pole automaton installed in the power supply shield of rustic property. Colonel will give an order to the captain during the connection of the device to the electrical wiring in order to completely remove the voltage.
Important! During the period of operation with the electrical wiring of the current supply to the equipment, the object must be completely overlapping, i.e. Remove voltage by shutdown.
The device, giving up under our start team of the bulb, is selected according to the type of wiring available. She may be:
- open - laid on the walls, predominantly folded from logs or timber;
- hidden - spent in the channels-strokes, heated in the brick, foam concrete, aerated concrete.
With open wiring, everything is extremely simple: the paths of eyeliner and output of the electric flow, like the locations of the connections, are determined by the naked amateur eye. To improve the bath with hidden wiring, a power circuit is required, with which you need to determine the point of possible installation.
Switches for wiring hidden and open type They differ constructively and externally:
- Hidden devices for the production of / off production are seized with walls, glad to holders only a beautiful protective lid. The entire filling of the device is "interpreted" in advance niche. The mechanism that gives the captain's teams is located in dielectric submerged, similar to a shallow glass of plastic. Its necessary to establish initially into the generated recess. Fix hidden picklers in plasterboard partitions using special spacers, brick and concrete Walls their "plant" on the alabaster or on building mixture. Outputs to switches for hidden wiring Sell \u200b\u200bseparately, they need to be selected depending on the material of the wall.
- Switches for an open power grid instead of a cup-shaped mounting device are equipped with a flat plastic or metal platform. It is necessary to attach galvanized self-drawing to wooden wall, Dowel-nails to brick or concrete.
Both variants of switches have an equivalent number of structural components. This is a peaver, a team mechanism and decorative protective parts made of precipitating flow of dielectric materials. For more information about the choice of switches, read on the website "Engineer" website.
General principles and installation algorithm
Installing both types of devices is performed by analogy. general principles and a single work algorithm:
- First, the conversion is attached, which is a bowl or platform;
- Then it is directly connected to the circuit breaker with the lights of the creation of faithful connections between the current-host wires and the command authority;
- Then the mechanism is fixed on the plate or in glass-beaten with screws or strut;
- At the end, the results of the effort are closed with a lid and put on the keys.
The main snag is to properly connect the wires to the operating command of the switch. And to cope with this problem, you need to deal with the connection scheme.
Switching device connection diagram
Non-compliance with the rules for installing the light switch is fraught with overheating, followed by sparking and closure. One more very unpleasant consequence - Saving voltage in wiring. Because of it, even after turning off the lamp, it is impossible to replace the distilled element, without feeling the charms of the blow by household electric stoves.
Mustocat yourself personally and property, remember the mysterious "phases" and "zoli". Find out and forever we remember what you need to connect to:
- Zero or, as accepted in the world of electricians, zero lived on the lighting device.
- Phase goes to the switch. Within the phase veins, the chain should be closed, in order for the light to light up and Gasla. It is with the right opposite to remove the switch to zero light will light up and goes out on the orders of the owner, but the lamp can be shifted only after traveling to the camshaft with a full shutdown of the bath from the power.
- From the lamp to the switch also goes the phase area. Disable and turn on the chain from the key clicks will be at the point of breaking the phase channel. Those. In a place where the segment of the phase leads to the light bulb begins, and the phase wire comes out from the switch.
So, a phase and zero wire must be tested to the lamp, and only one-phase switch to the switch. Note all these cunning interlacing are in the junction box. In fact, they are interested in homemade masters engaged in the installation of the switch in an underdeveloped room or have decided to upgrade the existing system.
All connections of conductive sites are performed in the junction box. In plastic channels or in the wall, connect wires is undesirable due to complications with the detection and repair of damaged areas. If not near the installation site of the junction box, it is possible to stretch the phase and zero from the inner panel.
Described installation principles color switch Apply both devices for the inclusion of two or more lighting points. Accordingly, they have two or more keys. The difference is that the segment of the phase from the lamp is supplied to each of the keys, the operation of which it must be controlled. The phase from the junction box to the switch with any number of keys is exclusively one.
Color and Marking of Channel Channels
In the prevailing majority of cases, the improvement of the contour with the new device owners of baths, houses, apartments trust electricians. Combining the junction box often just once and not with hand. Most often the reason for the application effort homemade Masters It happens to replace the switch when phase and zero channel channels are already connected to the installation point.
Attention. New installation The switch or its replacement is performed only with the entire range of wires forming the electrically conductive circuit.
In order for inexperienced electricians to have difficulty defining a phase with a zero, the external insulation of current-carrying livers has a "combat" color:
- phase veins will be covered with a white or brown shell;
- the blue color of dielectric protection will proclaim: it is zero;
- yellow or green kel different shades - Grounding.
According to color prompts and should be determined how to install and what to connect the light switch. Additional service The manufacturer is to apply the designation to the mechanism itself for a particular orientation on entry and exit issues. Indicatically connecting points LITERY L with a tide. For example, on a two-lying device L3 indicates the input of the phase. Next to him nothing will be revealed. On the opposite side of the device in a row, the connectivity points L1 and L2 are located, each of which needs to be displayed on a separate lighting device.
Stick or clamp: what is easier?
For simplicity and reliability of the formation of connections, the connection points of the switch are equipped with in power and screw fixtures:
- Castle contacts fade clamping cleaned over 1 cm spruce wire. In order to disassemble the connection, with opposite side The insertion is the button acting on the principle "pressed - released";
- Screw contact needs to be tightened with a screwdriver, pre-locating under the terminal about 2 cm stripped wire. Not a millimeter of isolation under the terminal should not be, otherwise it will be melted and will become a threat to the owners.
The principal difference in aspects of reliability between both options nobody is observed. However, stick it easier and faster. Therefore, switches with full contacts persistently advise sellers of building stores in inexperienced masters. Electricians agree with them.
How to install a switch switch
Russian bathhouses are predominantly wooden. Hidden to lay the electrical outline in them, there are few people. For the open wiring device, there are now a lot of pretty products in retro styleCovered with excellent insulation. The company will require a switch of an overhead type. That's about the sequence of its installation and let's talk.
Suppose we have acquired a switcher for open wiring. He is in the factory assembly, the key is one. Installation and connection of a new overhead switch light will be performed in the following sequence:
- Using a slotted screwdriver, carefully attribute and delete the key, then remove the protective and decorative lid.
- Disconnect the working mechanism.
- Disassembled. Only a plate of conversion remained in his hands. It has holes for fastening to the wall.
- We will make a plate to the installation site, just in case we note the point and line of the upper edge. Check for it clearly horizontal. Do not forget that all subsequent details will be attached to the opposite. If it is disturbed, then everything else in the tight steppe will go.
- We screw exactly the horizontally spacing platform with galvanized screws. Even a couple of mm should not be wrong - the wood "does not like" the rut of the ride.
- Wires cut with maximum accuracy according to the type of contacts. It is desirable that after all operations of excessive wires under the decorative lid it turned out.
- Connect the mechanism to the wiring, following the marking prompts and conforming with the color of the wire.
- Check the quality of the compound created by a multimeter with a more complex electric tester.
- Everything is fine? Finish the mechanism.
- We put the lid on her rightful place, snatch the key.
This is completed on this process.
Installation and connection of the closed switch in pictures
A completely simple process. Disassembled - competently installed and connected - collected.
Components of minimum, extra nuts after assembly will not be. It is impossible to confuse if you find out in advance what is connected to. Everything literally has to check own forces As a beginner electrician. The main thing is not to forget about safety rules, otherwise the current will check you for strength.
Many electrical appliances are equipped with switches installed on themselves, so they do not require special care: I bought a fan, and it is already on it - the switch or on the body, or on the wire. Such electrical appliances are often left on a network with a cord, constantly stuck into the outlet (although firefighters, usually, against). If the device is used on the case of the case, then it may not be a switch at all, for example, the iron is the simplest. Stuck - and earned, began to warm up.
Therefore, all the outlet of our electrical engineering to install switches separate on the wall usually does not require. That is, it or has a switch on itself, or not it is generally, or there is a switch, but it is automatic, and our participation does not require (refrigerator). However, it is important to know that the switches installed on the instruments and the switches that are on the wall, they do not differ in principle. Well, except that switches hanging on the power cord are made so that you can take them in your hand. But they, too, together with the rest of their numerous brother, - the essence of one.
Varieties of switches
In the electrical engineering, all opening / short-circuit devices are called short and clearly: the key.
Both types and sizes they have a different one - from invisible or microscopic silent electronic to huge iron, covered with oil. But the principle is as follows: they can closure chain, and can open. This is one feature. And the second is to memorize your last fortune.
There is a button that will work, turn on the light bulb or call on the door, for example, and then the spring is reset. But the switch on the buttons is still done so that the fixation takes place. For example, on powerful machines, the switch has two buttons: Start and Stop. This is the switch, only relay. You turn it on the start button, then the electromagnet is triggered and the start button is fixed, without letting it be free. On the stop button, you pick it up - the electromagnet circuit opens, and the Start button is released. Only it is in force technique, it is usually not found in everyday life. And in everyday life, a similar mechanism is implemented using mechanical latches.
Our household switches work mechanically. They installed springs that fit the pusher provide good contact In the case of inclusion, and spinning is the lack of contact in the event of a disconnection.
Household switches differ by execution (or on the wiring in which are used):
- outer wiring (external performance) - the wiring is carried out on top of the already decorated walls and other elements of the interior, the switch is all outside the wall;
- internal wiring: prepared and performed before finishing, is interpreted into the wall. Only switches and sockets are visible remaining in the walls and inscribed in the interior.
Usually, household switches are used for lighting. These are normally open commuting devices, and in the sense of installation unified under home wiring. You can functionably count more fewer subspecies: keyboards, push-button, lever, rotary, cord, sensory. And there are still switches with slow quenching (dimmers) and manageable buttons and keys that are not familiar to us or keys, and otherwise: twitching for the cord, in the case of cord, remotely, for example, three cotton in your hands. But the latter are not particularly needed, since they can be mounted anywhere, and not necessarily on the wall, most often on the chandelier itself or diode ribbon. And they can be considered not as an ordinary apartment switch, but as a means of automation.
Connection schemes
The switch must erode the phase that goes to the lighting device from the distribution box. Zero enters the lighting device directly, bypassing the switch.
Two options are possible.
Switch connections
N - zero wire
L - phase wire
As you can see, the single-block connection circuit switch is different. It is right - this is when the phase wire returns back to the distribution box, and it only goes to a lamp or chandelier in one twist. With a normally open contact of the switches in such cases, there will be zero voltage in both wires, and the phase will only go when the switches are connected.
So it is done when the wiring is carried out standard, but the scheme may seem intact when you do it with your own hands. Because the builders first pave the entire electrician, and then everything is attached and glued wallpaper. The owner can make repairs in one particular room, or makes it partly, without deleting everything decoration Materials. Therefore, it can be problematic to perform exactly how it prescribes such a scheme for connecting a single-wave switch. Especially if a new lighting device is installed somewhere, and the switch to it is installed directly below the lamp. Moreover, in the wires in this case it is very easy to get confused.
In order not to get confused and not to connect in the distribution unit ultimately to zero, you can use two cables, different in colors of insulation of wires. Or take one cable from several multi-colored wires, and on the lamp to serve blue and red, and the switch is brown and green, for example, to embed it into a red box. Then the diagram of a single-wave switch will actually look like this.
In this case, it will only be connected to the incoming phase and zero in the box: zero to a blue zero lamps, a phase to a brown wire going to the switch, and the green wire returned from it to connect to the lamp.
Previously both cables twisted: the one that goes on the lamp (blue and red) and the one that goes on the switch (brown and green). Colors can be chosen and others, most importantly, I recommend the zero wire always and everywhere indicate only in blue. Just as in the scheme where there is a grounding, grounding always leave the regular yellow-green striped.
Now everything is clear, it remains only to make hands.
Mounting switch
We start assemble from the junction box. First, we find the box that heads lighting in the area of \u200b\u200bthe room, where we spend the light. Only first
Installation of wiring must be carried out with compliance with all electrical safety rules. Since the work is carried out on a network, which is life-threatening, voltage 220/380 Volt AC, the most responsible actions must be carried out when the power supply machines are disconnected on the panel.
To work to use security tools.
When working with the phase voltage, it is necessary to make sure the presence or absence of the phase on the conductors using the voltage indicator. Search conductive cables hidden in the walls, to carry out contactless wiring indicators.
During fines, drilling, fastening of wires, glasses, with special care to carry out such works, as conductors can be under voltage in the wall.
We do everything in order.
- Remove the cover from the junction box, we determine the zero-coming zero and the incoming phase.
- We will find the routes of cable gasket from the box to the switch and to the lighting device. Place for fines.
- Place the place to install the switch.
- Measure two pieces of cable required length.
- We produce punching holes for the installation of the switch. We do it carefully not to please the wiring in the wall.
- We make a breakdown (fined) canvas under the cable. We do it carefully not to please the wiring in the wall.
- Processing the ends of the wire for connecting in the box, lamp and to the switch.
- We make the gasket and fix the cable brackets in the strokes.
- A glass of peasant is placed on alabaster and / or self-tapping screws into the hole. At the same time, the end of the cable starts inside the opposition to the hole.
- After the alabaster hardens, the wires are connected to the switch terminals. The mountable switch must always be open.
- The wires of the cable going to the lamp are connected to the terminal bar of the lamp. The zero wire must approach the terminal of the carving of the base, the phase (from the switch) to the terminal of the central contact.
- Connecting wires to wires in the distribution box. Wires are connected when the networks are disconnected.
- Turning the lighting automaton and checking the presence of a phase on the switch input terminal. Turning on the machine at maximum caution.
Now - turn on the switch - the chandelier works!
Content:In every home or apartment, periodically arises the need for. Among them, most often you have to decide how to connect the lamp through the switch. This operation does not represent a special complexity, and it is quite possible to fulfill it personally, not attracting specialists. In addition to the minimum knowledge of electrical engineering, it is necessary to observe certain rulesrelating to preparatory work And the installation itself. It is recommended even before the connection starts to consider the scheme for placing electrical appliances and apply it on the wall. Only after that you can start laying the wires and installation of electrical equipment.
Preparatory work
Before starting work, first of all, it is necessary to turn off the supply voltage. To do this, it is enough to turn off the machine and check the device no voltage.
- Switch. Depending on the need, one- or two-block model is selected. Each switch for the lamp will be slightly different from each other, since the circuits of connecting both devices are different.
- Wire or electrical cable. Selected in accordance with technical characteristics The current electrical network. You should draw special attention The amount of lived, their cross section, material and labeling.
- Junction box. At home, as a rule, plastic fireproof products that are not conductive are used. electricity, with small compact sizes.
- Connecting terminals, tape. Provided by PUE standards for connections and subsequent isolation of contacts.
- Fasteners. Need to fix installed products.
- Tester or indicator screwdriver. With their help, you can make sure that there is no voltage, since the electrical network before starting work should be completely de-energized.
- Flooring, Passatia, pliers. Apply to connecting conductors with each other.
- Hammer drill or perforator. We will need when the device is hidden wiring in the plaster.
When a single block switch connects, three wires must be gathered in the junction box. The first is the feed wire for the lamp with a switch, with a voltage of 220 volts, which is supplied from plugs or automaton. The second will be a two-tier wire, summarizing to the switch. The third wire goes directly to the lamp or lamp. It can be with three veins if the luminaire case is equipped with a grounding clamp.
After all the wires gathered in the junction box, it is necessary to remove the insulation and prepare for the subsequent cleaner. After that, you can proceed to the assembly of the circuit and direct connection.
Connecting the lamp and switch
Full assembly of the scheme is as follows. Connecting the switch is carried out in the phase break. At the time of shutdown it is turned off, the chain opens and the voltage to the light bulb is no longer served. The zero wire through the junction box is connected directly with the lamp. Thus, the phase passing through the switch allows the lamp on and off, as well as the repair and maintenance of the lamp.
The introductory phase wire, which comes from the machine, is connected to the same wire that goes to the switch. For this, it is best to use. Another phase returned from the switch to the junction box is connected to the feed wire connected to the lamp. Zero wires lamps and nutrition are also connected in the junction box.
After that, the connection scheme is visually checked. Wires must be properly interconnected. IN finished scheme All twists are additionally compacted with pliers, and the px tubes are put on top and fixed with a tape. Twisted wires neatly fit into the box, after which it closes with a lid.
Placing wiring in the junction box is performed as follows. Initially, it is necessary to bring the total feeding cable, and then the remaining wires going to. One luminaire wire is connected to the zero living main wire, and the other with the switch wiring. The second switch of the switch is connected to the media phase conductor. As a result, the working veins lamps are connected to the total electrical wiring through the switch.
Thus, the task is solved, how to connect the lamp through the switch with one key. This scheme underlies the connections of other switches with large quantity keys.
Double Switch Connection Scheme
Unprepared man when connected two-block switch Follows certain difficulties. Before installing, it is recommended to learn instructions on how to connect the switch to the lamp to avoid mistakes allowed by newcomers.
At the beginning, the feeding three-core cable is mounted with connecting it to a protective device. One of the wires is connected to the grounding system if it is available. Before starting work, the entire electrical network must be de-energized. From the protective device, the conductor starts to the junction box, after which it is supplied directly to the two-lying switch. The stock of the wires at each point of the connection must be at least 10 cm. Next, the wires connected to the lamp are becoming the box.
The ends of the wires must be cleaned of isolation, after which it is combined with each other, taking into account the color-based insulation colors. At the end of the installation you need to check the correctness of all connections. For example, at the entrance to the machine, the phase wires are located on the left side, and zero - with the right. After that, the wires are connected to the switch contacts according to the diagram applied on the back of the device mechanism.
How to connect the lamp via the switch from the outlet
Connecting the lamp from the outlet through the switch is carried out according to the standard diagram. That is, a phase wire is interrupted, and zero connects directly to the light source.
Connection is performed in a specific sequence:
- Fully de-energized home electrical network.
- Mounted junction box in which the wires are breeding from set outlet, Housings, supplied to the lamp and switch.
- One lived from the lamp connects to zero contact, and the phase enters the switch. Another phase that comes from the junction box is also summarized to another switch of the switch, forming a gap. Due to this break, the circuit power is turned on and off.
It has great importance right choice cross sections. It all depends on the magnitude of the load, that is, on the number of connected luminaires. Mandatory requirement is the minimum cross section copper wire, component of 1 mm2. For aluminum lived this value will be at least 2.5 mm2. In addition, the selection of section depends on the method of laying, so it is recommended to use to get the most acceptable result.
First of all, before choosing and buying, you need to decide what it is - the passage switch, for which it is needed, and what is the difference from the usual one, two and three-block.
A single-scale switching switch is necessary to control a single loop or line of lighting from several points located in different parts Rooms or all at home. That is, with one switch you turn on the lighting at the entrance to the room or the corridor, and the other, but already at another point, you turn off the same lighting.
Very often it is used in the bedrooms. He went into the bedroom, turned on the light near the door. Lit on the bed and the head of the head or near the bedside table turned off.
In the two-storey mansions - turned on the bulb on the first floor, climbed the stairs to the second and there it turned off. 
Selection, design and differences of passing switches
Before collecting such a control scheme, this is what you should pay special attention to:
1 To connect the passage switch light, you need three-core Cable - WDGng-Ls 3 * 1.5 or NYM 3 * 1.5mm2
2 Do not attempt to collect a similar scheme on conventional switches. The main difference between the usual trafficking lies in the number of contacts. Simple classrooms have two terminals for connecting wires (input and output), and passing - three! 
On simple, the lighting chain can be either closed or open, the third is not given.
The passage is more correctly called not a switch, but the switch.
Since it specifies the chain from one working contact to another.
By appearance, in front, they can be absolutely the same. Only on the keys of the passage can be present icon from vertical triangles. However, do not confuse them with cake or cross (more about them below). These triangles look in a horizontal direction. 
But on the reverse side, the whole difference is visible:
- at the passage of 1 terminal from above and 2 below
- In the usual one from above and 1 below
Many on this parameter are confused with two-block. However, two-blocks here will also not suit, although they also have three terminals. 
There is a difference in the work of contacts. When a single contact is closed at the passing switches, the other is automatically closed, and there is no such function in the two-blockable such function. 
Moreover, an intermediate position when both chains are open at the passable is generally absent.
Connecting the passage switch
First of all, it is necessary to connect the switch itself in the opposite itself. Remove the key and overhead frames. 
In the disassembled state, you can easily see three contact terminals. 
The most important thing is to find a common one. A diagram should be drawn on high-quality products on the reverse side. If you understand them, you can easily navigate it. 
If you have a budget model, or for you any electrical circuits dark forestThe help will come an ordinary Chinese tester in circuit ring mode, or a battery indicator screwdriver.
With the help of the probe tester alternately concern all contacts and are looking for the one on which the tester will "squeak" or show "0" at any position of the on or off key. It is even easier to make an indicator screwdriver. 
After you have found a common terminal, you need to connect a phase from the power cable. For the rest of the terminals, attach two remaining wires.
And which of them is where, there is no significant difference. The switch is collected and fixed in the opposite. 
With the second switcher, you do the same operation:
- Look for a common terminal
- Connect the phase conductor on it, which will go on the light bulb
- For the remaining connected two other veins
Diagram Connecting the wiring of the passage switch in the distribution unit
Scheme without grounding conductor
Now the most important thing is to properly collect the scheme in the junction box. There should be four 3 residential cables in it:
- Power Cable from the Lighting Machine
- Cable on Switch №1
- Cable on Switch №2
- Lamp or chandelier cable
When connecting wires, it is more convenient to focus on color. If you use a triple cable VVG., then he has the most common two color marking:
- White (gray) - phase
- Blue - zero
- Yellow Green - Earth
or second option:
- White gray)
- brown
- the black
To pick up a more correct phase in the second case, focus on tips from the article "" 
Connect the zero core from the introductory cable and zero-out-down on the lamp at one point through Vago terminals. 
Similar to Zero Wire "Earth" from the introductory cable, unite with the "Earth" of the exhaust cable to lighting. 
This wire is connected to the lamp housing. 
The phase from the introductory cable must be connected with the phase of the outgoing wire to the common terminal of the passage switch number 1. 
And the shared wire from the passage switch number 2 is a separate WAGO clamp with a phase residential cable to lighting. 
After performing all these connections, it remains only to combine interconnected (exhaust) veins with a switch number 1 and No. 2. And absolutely no matter how you connect them. 
You can even confuse colors. But it is better to still stick to the colors so as not to get confused in the future.
Basic connection rules in this scheme that you need to remember:
- Phase from the machine must come to the general conductor of the first switch
- And the same phase should exit from the general conductor of the second switch on the light bulb
- Two other auxiliary conductors are connected to the distribution unit
- zero and land are served directly without switches immediately on the light bulb
Cutting switches - lighting control circuit of 3 places
And what if you want to control one lighting of three points and more. That is, switches in the chain will be 3, 4, etc. It would seem necessary to take another passing switch and that's it.
However, the switch with three terminals is no longer suitable here. Since the connected wires in the distribution will be four.
Here you will come to the rescue, or how it is also called the Cross, cross, intermediate switch. His key difference is that it has four exits - two below and two tops. 
And it is installed just the same in the interval between the two passing. Find two secondary (not basic) wires from the first and second passing switch in the dispenser box.
Dispatternize them, and connect a cake between them. Those wires that come from the first are connecting - to the entrance (focus on arroges), and those that go to the second - to the output terminals. 
Always check the circuit holders! It is often that the entrance and access they have on one side (top and bottom). For example, a fire scheme for a cake LEGRAND VALENA: 
Naturally, it is not necessary to shift the cake of shifting in the dispenser. It is enough to start the ends of the 4th residential cable from it. And the switch itself, meanwhile, have in any convenient place - near the bed, in the middle long corridor etc. Light you can turn on and off from anywhere. 
The most important advantage of this scheme is that it can be changed to infinity and add how much emotion switches. That is, there will always be two (at the beginning and end), and in the interval between them 4, 5 or at least 10 cake. 
Connection errors
Many at the stage of searching and connecting a common terminal in passing switch make a mistake. Without checking the scheme, it is naive to believe that the total terminal is the one where only one contact.
In this way, they collect the scheme, and then the switches for some reason they work incorrectly (depend on each other).
Remember that on different switches, the overall contact can be anywhere!
And it is best to call it what is called "live", tester or indicator screwdriver. 
Most often with such a problem face when installing or replacing passage switches from different firms. If everything worked before, and after replacing one scheme ceased to work, the wires confused.
But maybe this option is that the new switch is at all and not passing. Also remember that the backlight inside the product cannot affect the principle of switching.
Another common error is the misconception of cross. When both wires, from the passage No. 1, plant on top contacts, and from # 2 to the lower. Meanwhile, the Cross Switch the circuit and the switching mechanism is completely different. And connect the wires you need a crosswise. 
disadvantages
1 The first of the shortcomings of the passing switches is the lack of a specific position of the on / off key, which is in ordinary.
If you have blocked the light and need to be replaced, with such a scheme it is not possible to understand, the light is turned on or off.
It will be unpleasant when when replacing, the lamp simply can blow up before your eyes. In this case, the easiest and reliable way Disable lighting automatic in the shield.
2 The second drawback - a large number of Connections in dispensing boxes.
And the more cards you have, the more their quantity will be in the distribution circuit. Connecting the cable directly by schemes without dispensing boxes reduces the number of compounds, but at times it can increase either the cable consumption or the amount of it lived.
If your wiring goes under the ceiling, you will have to lower the wire to each switch, and then raise it back. The best way Here, the use of impulse relays.
At this stage, it is difficult to imagine at least one house without light switches. These aggregates are there different speciesbut all of them are pretty easily installed, they can be completely connected to the network even a person possessing basic knowledge Electricians.
Instruments
Before moving the switch to the network, you need to prepare a number of instruments:
- curly, straight and indicator screwdriver;
- connector;
- casual knife;
- pliers.
Features Wiring Wiring
The circuit of connecting the switch depending on its type (the number of keys is taken into account) is a bit different.
Most simple option It is a single-wave switch connection, in which case everything can be done independently. In such a situation, in the distribution box, there are only 2 wires - zero and phase.
The wire of blue color (zero), connects with the same wire on the lamp. The introductory phase is initially moving to the device to turn off the light, after which it returns to the distribution box again, and then it is connected to the phase from the light bulb.
The main condition for connecting a single-block light switch is attentiveness, because even with all two wires, there are quite often situations when a person confuses the veins.
Connecting a two-layer switch will require large knowledge of electricians, it is justified by all the groups of lamps have a separate chain gap. As with a classic unit, two veins are present in the distribution box. The blue wire is still on the entrance to other wires of the same color.
There are ways to connect switches without a junction box, but they require large skills in the electrician and are performed mainly by professionals.
The phase is initially carried out on the break, on both buttons, then it is fixed in a predetermined recess. Outgoing wires go to each present group lighting devices Or two separate bulbs.
Be sure to consider the fact that rear end The housing contains three holes: two are placed on the left side, and one more right. Where only one hole is connected to the input phase, and there, where two holes are the output phase heading to the lamp.
When setting the light off aggregate with three keys, you need to act by analogy with the installation of the device containing two keys. Zero, as in the presented versions, are connected with zeros of each individual bulb group.
The input phase is directed to the gap, and then they are divided into three different phase conductor, each of which is sent to its own group of bulbs.
Connecting through a socket
If nearby the planned place of installation of the unit to turn off the light, there is a socket, it can be powered by phase and zero.
In order to connect the switch from the outlet, it turned out to be successful, you need to comply with such a sequence of actions:
Initially, you need to remove the flow of current from the outlet. Similar actions can be performed by removing the voltage from around the house.
You need to open the socket and check the voltage.
To the socket phase, the wire is connected, the second side of which is attached to the switching switch. On the output of the unit to turn off the light, the wire connected to the lamp is attached.
The wire is attached to the zero contact of the socket, the second end of which is connected to the output of the lamp. The protective wire is connected in the same way, only to the corresponding contact of the lamp.
Having completed the indicated manipulations, it is necessary to lay the wires, insulate the conductive sections and submit voltage to check the efficiency of work.
Special popularity at this stage of time began to use backlit switches, when they are installed, it is desirable to refer to a professional, since the incorrect connection of such switches may refuse the increased load on the wiring, as a result of which it will be combustion.
In the absence of basic skills in the electrician, it is worth refusing even from independent installation Switches containing one key.
Some photos of the switch can be found below.
