An inexpensive audio bookmark system is provided that includes a control interface in the form of an electrical plug/receptacle type adaptor for plugging into an electrical power source receptacle. The adaptor includes female receptacles for receiving a power plug from an audio or audio-visual device in the form of a tape or video cassette player. The adaptor is connected in series with a remote control push-button switch having a low pressure responsive push button actuator normally biased to an open-circuit position interrupting power to the tape player. When playing a books-on-tape recording or the like, the listener manually depresses the remote switch push button actuator to energize the audio device. In the event the listener is distracted or dozes so as to release the push button actuator, the audio device will stop playing, thereby maintaining the tape deactivated at substantially the precise point at which the listener has been distracted or dozes off. Thereafter, subsequent depressing of the remote control switch push button initiates play at substantially the point at which play was interrupted.
