ABSTRACT:
A switching circuit is disclosed which provides a plurality of switches which can be caused to open or close, a controller which can selectively draw current from a plurality of power sources connected in electrical communication with the switches and isolating devices connecting the switches to the controller. The controller is connected to a regulator and to one voltage interconnection and the regulator is connected to another voltage interconnection by two conductive paths which control individual switches that are associated with individual power supplying loads.
