ABSTRACT:
A switch remoting system for extending the function of an existing wired switch in a residence or other building, so that, in its extended function, the switch controls AC power available at one or more additional AC outlets. The basic system comprises two plug-in modules including a control unit and a remote switching unit. The control unit is plugged into an AC outlet controlled by the switch whose function is being extended. When that switch is actuated, the AC power transition and the resulting "on" or "off" power state is sensed and corresponding encoded switching control signals are generated and relayed to the remote switching unit. There, the switching control signals are decoded, and actuate an internal AC switch that controls AC power to an integral AC outlet receptacle in the remote switching unit. A lamp or other device plugged into the AC receptacle of the remote switching unit is thereby switch controlled by action of the switch whose function is being extended.
