First, let’s take a look at the components involved in wiring a 3-way switch. You will need two 3-way switches, a few feet of electrical wire, wire connectors, and a screwdriver. It’s important to ensure that the power is turned off at the circuit breaker before beginning any electrical work.
Start by connecting the black wire from the power source to the common terminal of the first 3-way switch. Then, connect the black wire from the light fixture to the common terminal of the second 3-way switch. Next, connect the white wires together and the ground wires together using wire connectors.
Now, connect the travelers – typically red and black wires – from the first switch to the corresponding terminals on the second switch. The travelers allow the switches to communicate with each other and control the flow of electricity to the light fixture. Once all the wires are securely connected, you can turn the power back on and test the switches to ensure they are working properly.
