3 way wiring diagram power at switch. The black and red wires between sw1 and sw2 are connected to the traveler terminals. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together. 3 way switch wiring diagram power at switch multiple lights source.

In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. The travelers actually pass the electricity between the two 3 way switches as well as the 4 way switches shown in the 4 way switching wiring diagrams. Pick the diagram that is most like the scenario you are in and see if you can wire your switch.

Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit. The black line wire connects to the common terminal of the first 3 way switch. Traveler wires are interchangeable on each switch.

Typical 3 way switch wiring nm cable. Red and blue wires link traveler terminals of both switches. The cable should also have a ground wire or a total of four wires in the cable.

Green for ground terminal. To illustrate the wiring of these 3 way switches switch boxes and fixture boxes are not shown but are obviously required for every application. Black for live or hot wire.

With these diagrams below it will take the guess work out of wiring. The system also requires three way switches. In the above 3 way switch wiring diagram at each switch the black wire gets connected to the copper or black screw.

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.
