Wiring schematic for a 3 way switch. This is only a wiring schematic and not the actual wiring method used for 3 way switch installations. Unfortunately not all 3 way switches are wired the conventional way. 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. Each part ought to be set and connected with other parts in specific way. Two very old three way switches are depicted in the photo above. Wiring diagram 3 way switch with light at the end.
Below is a simple 3 way schematic that can be applied to all three way electrical light switch connections. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. Assortment of 3 way switch wiring schematic. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together. Pick the diagram that is most like the scenario you are in and see if you can wire your switch.
