FIELD: engineering of devices for signaling and protection.
SUBSTANCE: device is made in form of cylinder mechanism of lock, containing cylinder positioned in body with channel for key, spring-loaded locking pins and pushers, made with possible prevention of jumping into key channel by means of their abutment by ends against abutment board, which is positioned at narrow angle to cylinder axis, and flat key with working shelves, which are made with possible partial standby insertion of key into key channel. Ends of spring-loaded closing pins, positioned in body, are made stepped in form of rods having lesser diameter, around which springs are wound. In the body oppositely to rods, isolated portion of electric wire is positioned, and round apertures are made with possible insertion of appropriate rods into them. Tear of electric wire by end of rod is performed when rod is moved for distance, greater, than length of excess of spring-loaded locking pin of this rod.
EFFECT: increased efficiency of device.
