ABSTRACT:
A touch controlled switch system operable by human touch inputs includes an intercommunication feature to enable communication between remote touch controlled switch units over a power line. The system comprises a transmitting unit including a first touch receptor operable by touch inputs for applying coded message signals to the power line and a receiving unit including a second touch receptor operable by touch inputs and a control switch circuit for operating a load coupled to the circuit in response to touch inputs applied to the second touch receptor. The receiving unit also includes a message sensing circuit responsive to the coded message signals on the power line for operating the control switch circuit in response to touch inputs applied to the first touch receptor. The system allows devices at remote locations to be operated either by touch inputs applied at remote receiving units or by touch inputs at one or more master transmitting units to generate coded message signals on the power line.
