Abstract

720,636. Mechanical switches without quickaction. CHANCE BROS., Ltd. Aug. 12, 1953 [Sept. 4, 1952], No. 22251/52, Class 38 (5) A rotary switch is provided with one or more movable contacts n each of which passes through a gap in the spindle h and is spring-pressed against a number of fixed contacts e and an annular fixed contact c in a different plane. The spindle is located as shown in Fig. 3 by a spring-pressed plunger o in the spindle and rollers q in the body of the switch. The switch body may be made in two or more parts secured together by screws.
