PURPOSE:To enhance the theft preventive effect for car by combining an anti- crime switch and an engine switch, and allowing the system to emit alarm tone, beam and/or put the engine out of function to start if the engine switch is operated without unlocking the theft preventive lock. CONSTITUTION:A serial circuit of an anti-crime switch BS, selected through operation of a theft preventive lock, and an engine contact switch ES is provided with a tone emitter C, a beam emitter L and/or a starter relay X. If the engine start is tried without unlocking the theft preventive lock, the tone emitter C and beam emitter L will give alarm, and the relay X opens the starter motor circuit. This enhances the theft preventive effect for car. |
