How to Replace a Single Pole Wall Switch

Step 1: Turn Off Power at Circuit Breaker
Start by opening the circuit breaker panel and turning off the breaker that powers the switch. If the breakers aren’t labeled, turn on the light, and try breakers until the light goes off. If you’re unsure or the switch wasn’t working, turn off the main house breaker to shut down the entire panel. Test to be sure the power is off by flipping the light switch a few times.
