ABSTRACT:
A radio receiver and its power supply are included in a circuit with a switch which is responsive to introduction of a force field, such as a magnetic field. When the field is activated, as by the introduction of a sufficiently powerful magnet, the switch is opened and the radio receiver is deactivated. Removal of the force field automatically restores the radio receiver to operable condition.
