Encoded electrical control systems for household applications each employ an encoder/transmitter that provides an encoded signal and a receiver/decoder which effectuates control of an associated device only upon receipt of a signal containing the code unique to that specific receiver/decoder. For household applications, a separate receiver/decoder, each having its own recognition code, is associated with each power outlet or electrical device to be controlled. A common controller includes an encoder/transmitter and a control switch for each device, along with means such as an rf carrier source and modulator, for transmitting all the encoder/transmitter outputs over the electrical distribution system. When a particular switch is actuated, the associated encoder/transmitter sends a signal containing the code of the corresponding receiver/decoder, which in turn effectuates the intended control function.

An encoded electrical control system for remote control of devices powered from a Common electrical distribution system, comprising: a controller including a switch and a control member, and an associated encoder/transmitter providing a unique, encoded signal in response to actuation of said switch,

An encoded electrical control system for remote control of devices powered from a Common electrical distribution system, comprising: a controller including a switch and a control member, and an associated encoder/transmitter providing a unique, encoded signal in response to actuation of said switch, said encoder/transmitter providing said encoded signal repetitively at a repetition rate determined by the setting of said control member, transmission means for transmitting the encoded signals from said encoder/transmitter over said electrical distribution system, and respective receiver/decoder means associated with each device to be controlled, each receiver/decoder means being connected to receive the encoded signals transmitted over said distribution system and to effectuate control of said respective device in response to receipt only of the unique code associated with that specific receiver/decoder means, and wherein the associated receiver/decoder means effectuates control of the associated device in proportion to the repetition rate of said encoded signal.
