ABSTRACT:
An anti-theft device employs a magnetically latched relay connected to the spark coil of a vehicle, a push-buttonswitch, and several multiposition thumbwheel switches for selectively setting the relay in positions where the spark coil is operational or inoperative and for maintaining both the operational and inoperative conditions of the spark coil without constantly drawing battery current, the initiation of the inoperative condition being achieved merely by actuating the push-button switch with the thumbwheel switches in the proper positions.
