ABSTRACT:
A toggle-type power regulator is adapted to shunt or open a power control circuit at opposite limit positions and has infinitely variable power control at all intermediate positions between the limit positions. A potentiometer incorporated in the control circuit comprises a pair of arcuate tracks of resistive and conductive material positioned on opposite faces of the control circuit substrate. Variable voltage output is achieved as the tracks are engaged or wiped by the opposed resilient contactors of a caliper which is connected for movement by the toggle. The regulator includes a one-piece dual blade switch assembly through which the toggle is yieldably held in the intermediate positions at which reduced power is supplied to the load.
