How To Replace A 4 Way Light Switch

By | August 10, 2022



Most homeowners understand the importance of replacing a light switch at some point in time, but few are aware of the intricacies involved with replacing a 4 way light switch. A 4 way switch serves as an intermediary between two 3 way switches. It allows you to control a single light from multiple points in your home, such as a stairwell. Replacing a 4 way switch is a bit more complicated than replacing a standard 3 way switch, but it can be done with the right knowledge and tools.

The first step to replacing a 4 way light switch is to identify the circuit wires. There will be two 3 way switches, each containing three wires. These wires will need to be identified in order to find the correct circuit without the possibility of damaging them. The two 3 way switches need to be labeled according to their corresponding wires. Once this is done, the 4 way switch can be removed.

The final step in replacing a 4 way light switch is to install the new switch. The circuit breaker should be shut off before installation begins, for safety reasons. The wires must be connected to the new switch according to the labels placed on them earlier. Once the wiring is complete, the switch can be mounted to the wall. Lastly, the circuit breaker should be turned back on and the 4 way switch should be tested to ensure that it is functioning properly.

Replacing a 4 way light switch is a straightforward process that can be completed in a matter of minutes. With the right knowledge and tools, any homeowner can do it. It takes a bit more patience and finesse than replacing a standard 3 way switch, but it does not need to be intimidating. So next time you need to replace your 4 way switch, don’t be afraid to handle it yourself!
