Abstract
A motor driven switch for use in operation between high current electrical systems and low current electrical systems. The motor driven switch includes a control circuit for operating the switch, which includes at least one switch contact movable between electrically open and closed positions. The switch is operated by a reversible direct current motor having a shaft rotatable in opposite rotary directions, upon control of the switch circuitry. The switch contact is operable to conduct high currents, and the direct current motor and associated control circuitry are operative to be controlled by low current systems. In a preferred embodiment, the motor driven switch controls distribution of current within an automotive electrical system.
