Wiring a 3 way light switch. This switchlight is designed for single 3 way light switches where two or more light switches control a set of overhead lights. This 3 way light switch diagram shows connections when the power comes into the first switch on to the second switch and then on to two or more lights switched by the 3 way circuit. 1 circuit power supply cable 2 electrical box where the light fixture is mounted 3 4 these wires must be connected to the common screw 5 light fixture.

Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. The white wire from the switch connects to the black wire from the circuit power supply cable. Three way switches allow for controlling a light fixture from two separate locations these are usually used at the top and bottom of a flight of stairs or at two different entrances to a room. When wiring a 3 way switch circuit we will be using a 3 wire cable known as romex coming from the source such as the breaker box.

Each 3 way switch in these examples are controlling the power source to the same load. The hot source is spliced to the white wire which should be marked as.
