Abstract
The present invention is for a bi-stable battery switch incorporated preferably for internal use into a remotely switchable storage battery, or, in the alternative, for external use with a battery. A bifurcated contact assembly incorporating dual bus bars is pulse actuated by a solenoid and cam arrangement to engage or disengage across opposing contacts. When engaging the contacts and when associated with high inductive loads, the first bus bar to advance initiates contact and assumes the arcing load, while the second bus bar to advance assumes the current load. When breaking contact and when associated with high inductive loads, the first bus bar to retreat breaks the current load and the second bus bar to retreat breaks the arcing load. Thus, the loads are shared to increase the durability and length of service of the switch.
