Abstract
An electrical contractor device (80) for controlling the flow of electrical power from a source of electrical power to an electrical device according to a command signal from a controller utilizing a rotary disc assembly (90) rotated by an actuator (169) where the rotary disc assembly (90) is comprised of a rotary disc (100) supporting a disc conductor (102) having a pair of contact pads (106, 108) joined by a pair of conductor legs (109, 113) and a center section (111) where the conductor legs (109, 113) are parallel and offset one from the other straddling an axis of rotation (103) where high flow of electrical current through the disc conductor (102) generates an electro-magnetic torque in the rotary disc assembly (90). The disc contacts (106, 108) make electrical contact with a corresponding number of stationary contacts (110,112) of a "turn back" design one of which is connected one to a source of electrical power and the second to the device whose operation is to be controlled were as the rotary disc (100) is rotated by the actuator means (169), the disc contacts (106, 108) make electrical connection with the stationary contacts (110, 112) and when the actuator (169) is not e…
