Abstract
A U-shaped or O-shaped metal strap (20, 30-32, 34) is attached in a belt-like manner around the insulating housing (2, 2') of a DC speed control switch to provide an external heat sink for a FET (22, 36) attached to the heat sink. Bosses (2f, 2h, 2g) on the switch housing project into holes (20e, 20b-32b, 34h, 34g) in the heat sink to position the heat sink on the housing. Formed terminal conductors on the FET plug into press-in terminations on the switch. A pair of mirror image battery clips (16) are trapped against opposite sides of the switch housing by the heat sink and an interposed insulator (18), the clips having cooperatively aligned depending legs (16e) forming battery terminal clips, and formed prongs (16c) that plug into press-in wire terminations on the switch. Holes (16d) in body portions of the battery clips surround bosses (2e) on the sides of the switch housing to interlock the clips against lateral movement.
