How to Wire a Single-Pole Light Switch Tired of your almond-colored toggle light switches, and want to update them with more modern screwless wall plates and rocker switches?

Buy a single-pole switch if there is only one switch that turns the lights on and off. If you have two locations that turn the lights on and off, you will need a three-way switch.
