ABSTRACT:
A dimmer switch assembly consists of a conductive yoke which has two insulation housings connected thereto which carry respective subassemblies for the dimmer switch. A cavity in the first housing receives the main power semiconductor device of the dimmer switch. The power semiconductor device is thermally connected to the yoke through a thin electrically insulative tape and has an active, non-electrically isolated, heat sink. A biasing spring within the first housing presses the power semiconductor device toward mechanical engagement with the yoke. The first housing assembly is fastened to the yoke by conductive eyelets which are insulated from the power semiconductor by the first insulation housing.
