Large cottages and country houses often use walk-through switches. Sometimes they are installed even in spacious three- or four-room apartments.
Passing switches are convenient in that they allow you to turn on the light in some room in one place, and turn it off in another.
For example, you need to walk along a long corridor at night. They turned on the light with a switch, which is installed at the beginning of the corridor, and turned off the second switch at the end of the corridor. Agree, is it convenient?
Many people who are not pros in the electrician do not know how to properly connect the passage switches in the house. In this review, we will consider in detail the classic connection scheme, which will be clear even to beginners.
Connecting breakers
A three-wire cable must be connected to the switches. One of the wires (in this case, red) is connected to a common contact.
Wiring is done in the junction box. Two three-wire cables from the switches and two two-wire cables must be brought into it: one supply cable, the second - from the lamp itself (light bulb).
First, the phase wire of the power cable must be connected to the red wire of one of the switches. And the neutral wire of the power cable must be connected to the "zero" of the light source.
In the next step, two blue and two yellow-green wires that come from the passage switches will need to be connected together.
Then it remains only to connect the red wire from the lamp to the red wire of the second pass-through switch. Connections need to be wrapped with electrical tape.
Details on how to properly connect the through switches, we recommend that you look in the video on our website.
