There are many types of light switches to control light fixtures in the home. Most come in assorted styles including toggle, slider, push-button or the popular rocker style. Some switches are available with smart technology that allows you to control light fixtures through remote connectivity. Below are different types of light switches with different functions to consider.

Before you install any type of hard-wired light switch, be sure to check your local building codes for specific installation requirements.

Single-pole

The most common light switch in the home. Controls a single light fixture from a single location.

Double-pole

Used for high-power appliances, such as electric water heaters, ovens, or air conditioner.

Three-way

Controls a light fixture from two locations, for example at the top and bottom of a staircase.

Four-way

This switch is used in conjunction with three-way switches to control a light from three or more locations like in a very long hallway or a large room with many entrances.

Dimmer

Adjusts the light output from a light fixture from nearly dark to fully lit. Available in single-pole, three-way and smart dimmers. Dimmer switches are available in assorted styles and vary in compatibility with different types of light bulbs.

GFCI

Also known as a ground fault circuit interrupter, this is a safety switch used in areas where water is present, such as bathrooms, kitchens and outdoors. It is designed to protect people from electrical shock by quickly cutting off power. CFGI’s are available in multiple categories, including tamper-resistant, weather-resistant, self-testing, indicator lights, space-saving and a safety nightlight.

Occupancy

This is a motion detector light switch that typically uses infrared or ultrasonic sensors to turn lights on when motion is detected. After a period of inactivity, the switch automatically turns the light off.

Cordless

Also called a wireless switch, this light switch doesn’t require a physical wire connection to the light fixture it controls. It uses a transmitter switch to send a radio signal to a receiver installed near the light fixture to turn the light on and off.
