How to connect a double switch

structure, advantages and disadvantages of a double switch

Dvuhklavishny switch is designed to control two different lighting from one place or two parts of one large unit.It is very convenient to turn the light in the bathroom and separate toilet.Often they are placed in the corridors outside the front door, so you can easily turn the light on and was on the street and in the hallway.

In order to have an idea of ​​what's inside and it looks like a double electric switches, look at its structure.

It consists of:

• housing;
• two keys;
• input and output phases.

Such a switch simultaneously connect three wires: one comes, two outputs for connection of lighting fixtures.

Similarly, looks and model-Key.In fact, dual switch consists of two single.The structure of some of these species may include the backlight, making it easier to search the switch at night.

Now consider all the advantages of this type of circuit.

• main advantage lies in the fact that one switch controls the operation of several light bulbs, which is why it is so popular.
• It can also adjust the brightness of the lighting in the room without difficulty due to its ability to turn off and turn on lights only part of what can make one-button switch.
• installing this type of circuit can significantly save on electricity and wiring, as it will need to stretch just one wire.
• Tandem switch is also very beneficial, because if it is placed in the street, to make protection against moisture cheaper and easier one, rather than a few scattered in different places.

Well, to the only drawback is the fact that if dvuhklavishny electric switches connected to two different chandeliers, which are located in different rooms, they can be confused at first, and not used to turn on lights not in the room, which is necessary.

How to connect your own double switch

to work on the connection of this switch does not differ from the normal connection.If it is good to understand that, in general, this is the two most common switch.

need to connect:

• flat screwdriver;
• Phillips screwdriver;
• stationery knife;
• side cutters;
• level.

To connect this type of switch is necessary to perform a series of steps.

Step 1. Turning off the electricity to the apartment.The switchboard all the levers or the plug must be turned into an inactive position.It will need to ensure safe operation.

Step 2. Now we have to prepare the wiring and to explore the characteristics of their location.As a rule, dvuhklavishnoe device has three wiring.

Step 3. Transactions need to be shortened to a length of about 10 centimeters.

Step 4. Prepare a small hole in the wall with a chisel for the further deployment of the wiring under the electrical switches.

Step 5. After this, connect the wires.It is necessary to clean them first, and then twist together and reliability squeeze the pliers, carefully insulated.

Step 6. Connect the two wires to the lights and immediately carry out the electrical panel from zero for each phase.

Note!Note that when connecting the wires to connect to each other should be made only from one material such as aluminum to aluminum.

Step 7. At the end of connection works must be put on the box and apply voltage to check the serviceability of electrical switches.It is set so that the common terminal is at the bottom.

To have a complete picture of this work, see special offer video tutorial, which will help deal with all the nuances of the connection.

chandelier How to connect to a double switch

Before performing any work on the lighting should protect themselves by turning off the voltage.To make sure there is no voltage, you can use the tester.

If the chandelier has five or more lights, then without dvuhklavishnogo switch can not do, because it has a three-wire system and allow to adjust the lighting to include only part of the light bulbs, but not all together.

When connecting the chandelier should pay attention to the label, which is applied on the terminal, the usual phase signed the letter L, and zero with the letter N. The chandelier with a few light bulbs has a number of wires, labeled similarly.

From the ceiling where the chandelier is attached, must be seen three cables, one zero and two-phase.Note that you need to pass through the switch is live wire.This is done so that in the course of repair works do not turn off the electrical panel, and you can just click the button switch - it is quite convenient.

Now that the lead is clear, proceed directly to connecting lamps to electric switches.To do this, find the phase wire.This can be done as follows: alternately include every key and at the same time to the wire to touch a screwdriver indicator.If it is lit, then the right cable found.

Only after all the necessary wires are found, they can be connected.We need to hang a chandelier on the shelves, and connect all the wires according to the markings on them, that is zero to zero cable and so on.

All wire connections should be after wrap tape with each other.It is necessary for the reliability and safety of the bond.
