Abstract
A rotary switch of sliding contact type for use in a torque converter of an automotive vehicle comprises a base in the surface of which a plurality of stationary contact plates are molded, a cover plate for the base plate suitably secured to the latter with a space for movably enclosing a rotary contact arm between the cover plate and the base plate, and a rotatable shaft fixedly received in the hub of the rotary contact arm. The hub is rotatably held between edges of corresponding openings formed in the base plate and the cover plate, so that, upon rotation of the shaft, contacts of the rotary contact arm slide across the stationary contact plates and can be stopped at positions precisely corresponding to predetermined angles of rotation of the shaft.
