types of switch

Electrical

The answer to 'types of switch' is that there are several common types of electrical switches used in homes and buildings. The most common types are light switches, toggle switches, dimmer switches, and motion-activated switches.

Light switches are the basic on/off switches used to control lighting circuits. Toggle switches have a small lever that flips up and down to turn the circuit on and off. Dimmer switches allow you to adjust the brightness of lights by varying the electrical current. Motion-activated switches detect movement and automatically turn lights on and off as needed.
