In recent years, there has been nothing less than a Renaissance in light switches. New switches offer a wide range of control, such as full-range dimming, a delayed fade from on to off, dimmers that remember a range of different pre-settings, switches that automatically turn lights on when a person is in a room, and central lighting control stations that can operate lights anywhere in the house. You can also control lights with hand-held, infrared, wireless remote controls. See information on good old single-pole, three-way & four-way light switches.

Some switches are operated with keys, timers, flat rockers, or, in the case of an outdoor switch, a waterproof lever. They may also be signaled by photoelectric eyes that sense light in a room or outdoors.

Some switches are paired up with receptacles (a "combination" switch), and others have a pilot light that lights when the switch is on. Outdoor switches, mounted in a special box, are operated with a lever.

Dimmers, which control the amount of electricity that flows and the amount of light available, can be operated with a toggle, dial, slide, switch, touch pad, or button (special dimmers are needed for fluorescent and neon lights and loads greater than 1000 watts).

Central lighting control stations allow you to operate all the lights in the house from one room, such as the master bedroom or living room, and can be programmed for lighting in different zones of the house at different times.

Switches should match the ampere and voltage ratings for the circuit. And if your home has aluminum wiring, be sure the switches are designated "CU-AL" for compatibility.
