Light Switches

In building wiring, light switches are installed at convenient locations to control lighting and occasionally other circuits. By use of multiple-pole switches, multiway switching control of a lamp can be obtained from two or more places, such as the ends of a corridor or stairwell. A wireless light switch allows remote control of lamps for convenience; some lamps include a touch switch which electronically controls the lamp if touched anywhere. In public buildings several types of vandal resistant switch are used to prevent unauthorized use.

Famous quotes containing the words light and/or switches:

    We live technologically, with man as the master of nature, man as the engineer, and let anyone who raises his voice against it stop using bridges not built by nature.... No electric light bulbs, no engines, no atomic energy, no calculating machines, no anaesthetics—back to the jungle.
    Max Frisch (1911–1991)

    I find television very educational. Every time someone switches it on I go into another room and read a good book.
