ABSTRACT:
An automatic power interrupting system for a vehicular control circuit including a relay switch having a contact connected between a power source and the supply terminal of a control circuit and a relay coil connected with the power source, a control switch connected between the power source and the supply terminal and with the signal input terminal of the control circuit and turned on only by an external force, a revolution detector for detecting engine revolutions and a switching device for turning the relay switch on when power is supplied to the circuit and off after a predetermined time period measured after stop of the engine based on a signal from the revolution detector. A second embodiment includes a kill switch connected together with an ignition circuit and a power source, a relay switch having a contact connected between the power source and the supply terminal of the control circuit and a relay coil connected between the power source and the signal output terminal of the control circuit, a starter switch connected with a starter between the power source and the supply terminal and with the signal input terminal of the control circuit, a revolution detector for detecting engine revolutions and a switch for turning the relay switch on when the power is supplied to the circuit and off after a predetermined time period measured after stop of the engine based on a signal from the revolution detector.
