Abstract
A control circuit for operating a lamp or other electrically operated device using a conventional wall socket outlet that is selectively energized under the control of a conventional wall mounted switch. To permit the lamp to be independently controlled using either the wall switch or the lamp switch, a wall adapter unit is employed that plugs into the wall outlet and into which the lamp's power cord is plugged. Sensing means are employed to detect the operation of either the wall switch or the lamp switch to control an electrically operated switch which turns the lamp ON and OFF whenever either the wall switch or the lamp switch are operated. Different embodiments are provided for use with conventional electrical wiring and with either a conventional lamp or lamp incorporating additional circuitry to adapt it for use with the wall socket adapter.
