The chandelier is a set of single-lamp fixtures assembled into one original design. It is not only a decoration of the room, but also a powerful source of lighting. The maximum operating mode of the chandelier is not used so often (mainly at family celebrations, etc.). Most of the time, the luminaire operates in an economical mode (when not all the lamps are turned on, but only a part of them), while the level of illumination does not cause a feeling of discomfort in a person. Operation modes are controlled by a double switch.

Next, consider how to connect a chandelier to a double switch. How is the electrical circuit of the lamp assembled? Knowing the basics will provide an opportunity to better understand how to connect a chandelier to a double switch. So, scheme. As a rule, three wires come out of the chandelier. One of them is black - this is the zero working wire. He is attached tothreaded parts (side lobes) of all cartridges. The other two wires are phase conductors that are connected to the central contacts (reeds) of the cartridges, each to its own group. Sometimes there is also a fourth wire, painted yellow with green stripes - this is a protective conductor. It is attached to the metal parts of the lamp. How to connect a chandelier to a double switch if it is already installed? In this situation, it remains to connect the wires coming out of the chandelier with the conductors coming out of the ceiling. In this case, it is necessary to determine the phase and zero working conductors to which the lamp will be connected. Phase conductors can be identified using a voltage indicator. To do this, turn on both keys of the switch and check for voltage on the wires coming out of the ceiling. On two wires, the indicator will show the presence of voltage, on the third - absence. This third one is the zero worker. It connects to the zero conductor of the chandelier (black). Two phase wires are connected to the phase wires of the chandelier in any sequence. The connection must be made using a terminal block or clamp terminal.
How to connect a chandelier to a double switch if it is not already installed? Usually three wires are connected to the place of its installation. Voltage is supplied through one wire, and the other two are connected to the chandelier. The switch itself has three terminal connections. One of them is common, and the other two are turned off with the help of keys orconnect to the common. The wire through which the switch is energized (phase) is connected to a common contact (it is determined using a voltage indicator). Two other wires - to the remaining terminals of the switch in any order.
What to do if additional wire is needed
It often happens that only two wires are suitable for a chandelier and a switch (usually such wiring exists in old buildings). In this case, a reasonable question arises as to how to connect the chandelier to a double switch in this situation. To do this, you just need to stretch an additional wire between the switch and the chandelier. It must have a section no less than that of the existing wires.
You can, if necessary, connect the chandelier to two single-key switches. How to connect a chandelier to two switches can be easily understood by studying the above material. In this case, the incoming phase conductor is connected by a loop to the contact of the second switch.
Connecting a chandelier to a double switch or just a switch requires safety precautions. To do this, it is necessary to turn off the voltage from the place of work.
