Switches & Dimmers - Switches & Dimmers

A light switch opens or closes an electrical current to turn on a light fixture, ceiling fan or similar electrical device. Besides lighting up a room, some light switches incorporate special features, like motion detectors, to make moving around in your home safer and more convenient. This buying guide will help you understand the types of light switches available, so you can feel confident you’re selecting the right light switch for any room in your home.

Tip: Before you replace or install a light switch, it’s important to make sure the new switch matches the amperage rating and voltage of where it’s being installed. 15 amp switches should be connected to a 14-gauge wire, which is found in most homes. For commercial or industrial switches, 20 amp switches should be connected to a 12-gauge wire.

Light Switch Styles

Select a light switch that is compatible with the circuit where it will be installed. For example, if a light is controlled by one switch, you’ll need to replace it with a single-pole switch.
