ABSTRACT:
A rotary electrical switch is provided of the type that includes a stator body of substantially cylindrical shape having a cylindrical opening coaxially disposed therein. The stator body includes a plurality of electrical contacts embedded in the stator body at circumferentially spaced positions therearound and extending radially inward from the cylindrical opening in the stator body and having a pair of parallel disposed planar contact surfaces, all of the contacts being disposed in a common plane orthogonal to the longitudinal axis of the cylindrical opening. A rotor body is rotatably disposed in the cylindrical opening and a contactor clip including a pair of contactors electrically and resiliently engaging both planar contact surfaces of respective ones of the contacts is constrained to rotate with the rotor body. Each of the electrical contacts includes a pair of wedge-shaped edges for easy entrance of the planar contact surfaces in between the pair of contactors as the rotor is rotated in either direction. The method includes the manufacturing of the electrical switch particularly the manufacture of the electrical contacts and the wedge-shaped surfaces thereon by chemical milling.
