Abstract

712,935. Automatic exchange switches. SIEMENS & HALSKE AKT.-GES. March 14, 1952 [March 14, 1951; Oct. 11, 1951], No. 6749/52. Class 40 (4) 'In a rotary switch, the off-normal, decade, and like contact springs 20 are arranged radially round the switch shaft 2 and are controlled by a cam wheel 10 through levers 14 which are pivoted to the switch frame 1. The contact springs 20 are secured in a recess in the underside of the frame 1, and the mounting of each lever 14 is adjustable, Fig. 3 (not shown). One of the levers 14 co-operates with a graduated frusto-conical ring 25 to form a wiper-position indicator. The switch shown is driven by a step-by-step electric motor M.
