A light switch opens or closes an electrical current to turn on a light fixture, ceiling fan or similar electrical device. 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.
Toggle: A toggle light switch is the most common style. It has a single toggle that sticks out from the faceplate. The toggle is switched up or down to turn the light on or off.
Rocker: A rocker light switch operates in the same way as a toggle switch, but the design differs. It is wider and flatter than the toggle switch. It also requires less pressure to operate, making it a good switch style for accessibility.
Push-Button: The push-button light switch style is an older design than the toggle switch, but enjoys resurgences of popularity from time to time.
Touch Light: The touch light switch relies on capacitance to operate. Touching the surface alters the electrical field between the touchpad's outer surface and the inner surface, which causes the light to trigger.
Single Pole: A single pole light switch is the most common type of switch. It controls one fixture from a single location. It is easy to install or replace, and there are a variety of colors and styles available.
3-Way: A 3-way switch controls one fixture from different locations. It is often used in stairways, halls and large rooms. It is slightly more complicated to install.
4-Way: A 4-way switch controls one fixture from three locations. It is commonly used in large rooms. One 4-way switch must be used with two 3-way switches in a 4-way circuit. This is also more complicated to install than a single pole switch.
Multi-Location: A multi-location switch controls one fixture from three or more locations. Use in large spaces where having multiple controls adds convenience and safety. This is more complicated to install than a single pole switch.
