Abstract : The patent relates to control apparatus provided to intercommunicate transmit-receive systems such as radio sets one with another or with a telephone network. First and second signal processors convert a signal input from either of the systems into a form capable of energizing a switch which, in turn, closes a relay coupling the input from one system into the other. Also, the circuit for applying the incoming signal to either one of the signal processors, such as the first processor, includes a normally-closed relay of the switch of the other processor, i.e., the second processor. Therefore, intercommunication is voice-operated since and incoming audio signal transmitted into either system activates a switch of that system to communicate its transmitting system with the other.
