Patent ID: 7497582

Claim:
A device for adjustably providing power to at least one electrical load, the device comprising: a rear body member; a plurality of terminals configured to be coupled to a source of the power and at least one load; a power control circuit disposed in the body member and coupled between the plurality of terminals and the at least one electrical load, the power control circuit including at least one variable control mechanism coupled to at least one series pass element, the at least one series pass element being configured to provide power to the at least one electrical load in accordance with the at least one variable control mechanism setting; a front cover assembly connected to the body member, the front cover assembly including at least one switch mechanism coupled to the at least one variable control mechanism; a heat sink disposed between the front cover assembly and the rear body member; and a ground tab connected to the heat sink by a fastener and configured to extend in a direction substantially normal to an interior planar surface of the heat sink into the rear body member, the ground tab having a higher thermal resistance per unit width than the heat sink, the ground tab including a ground terminal configured to accommodate a ground screw.
