how to wire 3 way light switch diagram

Three-Way Light Switch Diagrams can be intimidating to the novice do-it-yourselfer, but with a few simple steps, wiring a three-way light switch is easy. Installing a three-way switch is a great way to add convenience and functionality to any room. By having two switches which control one light you can control the lighting from multiple locations in the room. Wiring a three-way switch correctly requires attention to detail and a clear understanding of the instructions.

When wiring a three-way switch, safety is of the utmost importance. Before beginning any wiring project, it’s important to turn off the power to the circuit. To wire a 3-way switch, you’ll need either a flathead screwdriver to loosen and tighten the screws or a voltage tester to make sure the power is off. Always wear safety glasses and rubber-soled shoes when working with electricity.

Now, that safety is taken care of, let’s begin. To wire a three-way switch, you will need two 3-way switches and one 14/2 or 12/2 Romex cable. You can use either single pole (SPST) or double pole (DPST) switches. To begin, connect the black wire coming from the Romex cable to the common terminal of the first switch. Then, connect the red and black wires to the traveler terminals of the same switch. Repeat this step for the second switch, being sure to label each switch’s travelers with a piece of tape. Finally, connect the two switches together, using a third piece of Romex cable. Once the connections are complete, you should be able to turn the lights on and off by flipping both switches. Congratulations! You have successfully wired a three-way switch!
