Three Way Switch Wiring Diagram With Multiple Lights

No more fumbling in the dark.

Three way switch wiring diagram with multiple lights. The most important rationale is that there are several ways that a three way switch can be wired. Here the source is at the first switch sw1 and 3 wire cable runs from there to the first light l1. Our easy to follow 3 way wiring diagram changing from a single pole to a 3 way light switch allows you to turn on any light from multiple locations such as at the top and bottom of a staircase or both ends of a hallway. 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.

Now discussing 3 way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. Wiring a 3 way switch with multiple lights in this circuit two light fixtures are shown but more can be added by duplicating the wiring arrangement between the fixtures for each additional light. 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. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
