Abstract
An improved motor driven switch is provided. A control system employs the improved motor-driven switch in series with a battery to disconnect the battery from a load when the energy level of the battery drops to a predetermined level. The system comprises an overdrive circuit to ensure that the motor drives a gear train to sufficiently close a gap between a movable switch plate and contact plates in a switch-closed position to reduce switch contact resistance.
