Automotive battery power circuit breaker

Claim 2

A dual coil solenoid operated automotive battery power circuit disconnect master switch installed preferrably on the ground side of the battery and having a movable plunger with an integral contact ring and a belleville spring system, the contact ring being located such that disconnect or connect of battery power is effected due to its position with respect to the battery ground and vehicle ground terminal ends which extend through the solenoid body and are located within the inner cavity, and said solenoid having dual coils with windings in opposite circumferential direction such that the force imparted to the plunger due to current flow within the coils is in one direction for operation of one coil and in the opposite direction for current flow in the other coil, and each coil having a separate exterior terminal for attachment of a conductor lead from the vehicle ignition switch such that, depending on the selected position of the ignition switch be it clockwise or counterclockwise, one coil is energized to effect plunger movement for battery disconnect and the other coil is energized for battery connect, and which plunger has integral with it or acting on it a belleville spring system which is capable of holding the plunger in the open or closed positions so that continuous solenoid power is not required to maintain the plunger position, the plunger position being determined by the solenoid coil last energized by the operator manipulating the ignition switch and which master switch having additional terminals for battery ground and vehicle ground and a solenoid body having a mounting provision, and which master swtich when open provides the desired result that no short circuit is possible at any device or accessory and not even at the positive or power terminal of the battery itself.

Claim 5

An automotive battery power circuit breaker which disconnects the circuit at one of the battery cables equivalent to removing one of the cables from the battery terminal, and which is manually operated to break and restore electrical continuity across its terminals by using a non conductive sleeve which is open on both ends and which has a right hand internal thread at one end and a left hand internal thread at the other end, which thread configurations receive corresponding male threaded terminals which are brought into firm contact or are separated depending on which direction the non conducting sleeve is rotated, and the rigid mounting of said disconnect switch being provided by the bolted connection of one terminal to the vehicle ground such that a housing or closure for the switch is not required for mounting, and which switch consists of not more than 3 components.
