Title: Distributed power switch for modular systems

Abstract: Power is fed from a pair of power supplies to each one of a plurality of load circuits through a distributed power switch. A plurality of switch means are each associated with a respective one of the load circuits for connecting it to one of the power supplies in a primary manner and to the other power supply in a secondary manner. Upon failure of its primary source of power, each switch means is effective for automatically connecting its load circuit to its secondary source of power.
