Abstract
Abstract A remote control receiver responds to pulse coded remote control signals for actuating a switch that in turn acts to deliver power to a device to which it is connected. The receiver response to control signals having a variety of code formats from any one of a variety of existing remote control transmitters. Thus, a remote control transmitter originally intended for controlling a specific device such as a television set can also actuate the switch to control a second appliance to which it is connected, such as a lamp.
