Abstract

605,675. Regulating switches. WYNNE, A. C. Jan. 3, 1946, No. 233. [Class 38 (v)] In a rotary switch suitable for transformer tap changing, a ball l mounted in an adjustable housing k co-operates with recesses m in a disccontact c to lift the contact finger j while it passes from one contact stud b to the next. The ball may also co-operate with studs in the disc c to form limit stops. The recesses m may be replaced by radial ribs on the disc, and the ball l and housing k by a peg.
