Dimmer switches can dim or brighten lights, rather than simply turning them on or off. \
Dimmer switches are designed to work with different types of lights. For example, there are dimmers made to work with LED bulbs and those made to work with incandescent or halogen bulbs. \
Some dimmer switches are made with the same configuration as single-pole light switches, which means you can use the same method to install dimmer switches once you know how to install a single-pole light switch. Choose a dimmer switch that is made for the type of light bulb you want to dim, use the same method for wiring a single pole switch, and everything should work just fine. \
