Varieties of Specialty Switches

If you have power tools or other devices that you don't want children to play with, consider installing a tamperproof switch. Operated only with a key, it can be wired to control the receptacle to which such items are connected.

For security in your backyard, or to have a light automatically greet you as you approach your house, choose a motion-sensor security switch. Its wide-angle infrared beam detects motion and turns the light on automatically. With most units, you can choose how long the light will stay on.

A pilot-light switch has a little bulb that glows when power is flowing through the switch. Use it when a fixture or appliance is out of sight. Closet lights, attic exhaust fans, basement lights, and garage lights often are controlled by pilot-light switches.

If you need to squeeze both a switch and an outlet into a single box, use a switch/receptacle. Also use this switch to easily add a receptacle to a room. This switch can be wired so the receptacle is live all the time or wired so the switch controls the receptacle.

A programmable switch comes with digital controls and can be programmed to turn lights on and off up to four times a day. This type of switch is useful for security and deterring burglars when you are away from home.

A time-delay switch has a dial that can be set to leave a fixture running for up to 60 minutes. Use one for a vent fan, space heater, heat lamp, or garage light.
