Three Way Light Wiring

In this diagram the electrical source is at the first switch and the light is located at the end of the circuit.

Three way light wiring. First run a 2 wire cable from the wall power to the black screw on 1 of the switches. The black and red wires between sw1 and sw2 are connected to the traveler terminals. Regardless of what 3 way switch wiring diagram you re following you ll need to use a 3 wire cable to connect the two 3 way light switches. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.

To wire a 3 way light switch you ll need 2 3 way light switches 2 2 wire non metallic cables 1 3 wire non metallic cable and 2 6 inch grounding wires. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire. Wiring diagram 3 way switch with light at the end. 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.

As it is three way switching wiring connection we have used two switches one is ordinary 3 way switch and the second one is 3 way pilot light switch. As the purpose of this 3 way switching wiring is that to control the light bulb from two different places same like the three way switching in staircase wiring while using pilot light switch. Three wire cable runs between the switches and 2 wire cable runs to the light.
