AUTOMOTIVE ANTI-THEFT SYSTEM

摘要

An anti-theft device for automotive vehicles that precludes operation of the ignition circuit if the ignition switch is tampered with. Two embodiments are disclosed that may be combined in a single system. In one embodiment, a micro-switch is placed in the ignition circuit and is connected to the lock by means of a frangible element. If the lock is removed the frangible element breaks and opens the switch thus disabling the circuit. In the second embodiment, an anti-theft lock is provided that operates on the structure that interconnects the lock to the ignition switch and engages upon removal of the lock to preclude operation of the ignition switch.
