Three Way Switch Wiring Diagram With Multiple Lights

How to install a 3 way light switch overview.

Three way switch wiring diagram with multiple 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. Wiring a 3 way switch isn t that difficult. 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.

The most important rationale is that there are several ways that a three way switch can be wired. 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. 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 light switch.

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. The answer to how it works is to have an extra hot wire that runs between the two switch boxes.
