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 flashlights, vehicles, and other devices.
