Patent ID: 8487722

Claim:
A thermally managed electromagnetic switching device comprising: a current carrying component set switchable between a closed, current carrying state and an open, current interrupting state; and a thermally dissipating component set that functionally supports and electrically isolates said current carrying component set in said open state, said thermally dissipating component set comprising a thermally conductive polymer and being cooperatively structured to transfer heat away from said current carrying component set in said closed state to dissipate thermal energy, wherein said thermally dissipating component set comprises a base and a cover coupled to said base; wherein said cover and said base are made of the thermally conductive polymer; wherein said current carrying component set comprises a pair of electrically conductive fixed contacts carried by a pair of bus bars; and wherein said pair of bus bars are mechanically interlocked or chemically bonded to the thermally conductive polymer of said base.
