In [[electrical wiring]], a '''light switch''' is a [[switch]] most commonly used to operate [[electric light]]s, permanently connected equipment, or [[AC power plugs and sockets|electrical outlets]]. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by [[dimmer]] switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in [[flashlight]]s, [[vehicle]]s, and other devices.
