ABSTRACT:
A variable resistance control includes a metallic structure plate that functions as a heat sink and that provides both a collector and terminals, a body that is molded onto the structure plate, a resistance element that is deposited onto the body and onto portions of the terminals, a contactor, and a driver. In one embodiment, additional miniaturization is made possible by bending a tab portion of the structure plate between two of the terminals to form a stop lug for limiting rotational movement of the driver.
