ABSTRACT:
A telephone silencing system is provided for use with at least one telephone receiver and an external telephone line electrically connected with the telephone receiver. This system includes a switch electrically connected in series between the telephone line and the telephone receiver. The switch is actuatable between a closed position, in which the telephone receiver(s) is connected to the telephone line, and an open position, in which the telephone receiver(s) is electrically disconnected with the telephone line. A receiver is operatively connected with the switch actuated between a closed and open position in response to a preset signal. A transmitter, in turn, when actuated, generates the preset signal to the receiver to thereby actuate the switch between its closed and open position.
