Wiring diagram dvuhklavishnogo switch: Stages

Important moments in the issue of how to connect a switch with two keys at home

Agree switch with two buttons - an engineering design, are practical and easy to use. As they say, from a single point, you can control several lamps or bulbs in the chandelier.

Putting tools for installation switch

Each wizard in the economic arsenal exists a standard set of tools, which is necessary for the repair of fixtures or electrical wiring. This bag must be included:

• pliers with side cutters;
• Painting knife;
• Screwdriver Set;
• good rubber gloves;
• special insulating tape or tube;
• self-locking clamp;
• screw clamp;
• drill, cable (if the wiring prokidyval the first time).

Preparatory activities, to be aware of

Before proceeding with the installation dvuhklavishnogo switch and connect it to the light, perfectly acquainted with the safety regulations for this type of work. Unfortunately, many people ignore this fact, so we decided to limit ourselves to an extremely important point:

1. Do not forget to disconnect the room. Without this manipulation to start connecting the lighting control is extremely dangerous.
2. Determine which of the conductors of the cable is a phase which - zero. Deal with it will help a special screwdriver indicator. When phase touch lamp lights on it.
3. Prepare all the insulation material. It may be silicone or rubber tubes, insulating tape and other materials that prevent the breakdown of high potential.

Detailed wiring diagram switch on the two light bulbs in the chandelier home

An experienced electrician can independently read a wiring diagram of the circuit breaker with two keys and install the device without watching the video tutorials. However, for beginners, this task is only by following the appropriate algorithm. Let's decipher how the given scheme.

Pay attention to the design dvuhklavishnogo switch depicted in the diagram. He has two keys that are opened and closed by pressing the button alternately. Zero and earthing conductor suitable for the light source directly from the switchboard, and from the switch provided only phase that exits the pre-ground angle and then passes through the break contacts of two keys switch. The method of distribution conductors in the junction box cover in the instructions in the next section.

Installation and connection dvuhklavishnogo switch

Connecting dvuhklavishnogo switch must fully comply with the scheme discussed above. Perform the installation using the following instructions.

Illustration	Description of the action
Present on the electrical panel electrical cable, wherein two insulated conductors: phase (white) and zero (white-blue, or blue).
	Null connect conductors of the electrical cable coming from both zeros bulbs.
Twisting together yellow conductor from the switch to the first conductor white bulbs.
	Interconnected bulbs second phase and zero output from the switch.
All the resulting twist must be insulated. Ideal to wear on their caps.
	We serve design and collect voltage thereto.
If both lamps are working properly and in turn light up when you switch the rules, then the installation is correct.

How to connect the chandelier with three lights to switch dvuhklavishnomu

Many would-be electricians, not knowing how to connect a switch with a chandelier dvuhklavishny to be equipped with several lights, simply connect the light source to a single key. However, this manipulation is incorrect, since all control features are not enabled.

Consider how the diagram looks more predetermined connection. As you can see from the diagram, we need to divide the wires that go to patrons chandelier in place of their connection to the two groups. One group will be the first branch of the key switch, and the other - the second.

The mechanism connecting dvuhklavishnyh-through switch does not look like a way to connect devices ordinary design.

In two places in the room prepared inserted switches. Remember that they must be fairly long contacts. Further there is the placement of all fixtures that are connected to this system. With the help of trohzhilnyh cable connection is made according to the diagram shown. Twisting all six contacts should take place only in distribution boxes. It is not allowed to contact the conductors directly with each other in the wall or in front of the switch.

Connecting dvuhklavishnogo light switch with socket: decoding scheme

To properly perform the installation of the unit, which combines plug and switch button, you must act according to the scheme depicted below.

The algorithm is as follows:

• outputted from the main shield cable with two conductors: phase and zero. It connects to the contacts in the switch box. By dual cable connects the lamp and the switch with the socket;
• junction box comes three cables coming out of the installed unit. The lamp is connected one living to zero, and the second - to switch the free terminal;
• if at block "+ socket switch" grounding conductor is provided, it must be connected to the same conductor in the manifold.

How to connect dvuhklavishnogo switch backlit own hands

Not knowing how the two-button switch with light, it is impossible to speak about the possibility of his right connection, so consider what components are included in the control structure by image below.

The phase arriving at the switch type, connected to the terminal L. Coming up with the contacts L1 and L2 phase is spent on lighting. In operation, the movable contact closure occurs L1, L2, L to each other. Direct lighting, which is equipped with our switch consists of a resistor and a neon bulb, which are soldered to the terminals L and L1. When the switch is in the off position, contacts L and L1 are open, the voltage across the filament comes to neon diode, causing it to light up. When the key switch changes position, the contacts are closed, resulting in lamp operation, thereby stopping the power supply to the illumination.

Subtleties connect two-button switches in homes with different earthing systems

Depending on the novelty of the power in the house, and it is changing the way the ground. This indicator affects the difference setting two-button light switches for grounding-type TN-C systems, TN-S, TN-C-S.

Under the scheme we see that out of the total of the electrical junction box in the coming phase (red) and zero (blue). Zero conductor connects with the corresponding contacts on the two lamps. At that time, when the phase of the switch comes on contact L, then exits the contacts L1, L2 or "1", "2", depending on the model. Further, the conductor of the first contact via junction box goes to the first lamp and the second conductor, respectively, - to a second source illumination. All wire connections in the diagram displayed in bold dots.

Wiring diagram dvuhklavishnogo device will be produced in a similar way as the previous one, the only difference is the presence of yellow-green grounding wire coming out of the electrical panel. Protective cable as "phase", and "zero", comes together in the junction box. Where it leaves only the lamp and connected to the corresponding color on the cable.

Errors that occur when connecting the circuit breaker with two keys

Even experienced electricians are able to connect properly, and it may be different reasons: fatigue, redoing someone else's work and other. In any case, the most common errors are:

1. Connecting zero (blue) wire to one of the "phase" of conductors (red, yellow or brown). Zero should always be connected with the zero directly into the manifold.
2. Connection of "phase" of the supply conductor on one of the off-L1 or L2 contacts ( "1" or "2") when it is necessary to carry out connection to the common terminal L. In this case, the chandelier will light only while pressing two switch keys, otherwise the lighting will be.
3. The conclusion to the switch Explorer "zero" instead of "phase". In this case, the voltage will always be present on the base bulb. Accordingly, it is possible to feel the first light bulb replacement.

Always be careful when working with electricity. Otherwise you run the risk of a strong electric shock that causes dangerous consequences for the future functioning of the body.
