ABSTRACT:
A cut-off device for engine starting systems is disclosed. The cut-off device has a cut-off relay unit and prevents electric current of a storage battery from being applied to the magnetic switch of an activated starter motor, thus positively preventing the activated starter motor from being restarted carelessly. The device has a movable terminal, which normally connects the keybox assembly to an ST-terminal of the magnetic switch thereby closing a circuit for the starter motor but selectively separates the keybox assembly from the ST-terminal thereby opening the circuit for the starter motor after the motor is activated. In addition, an alarm means is provided on the cut-off relay unit. The cut-off device allows both the engine and the starter motor to be effectively used without being damaged within their expected life spans.
