Abstract

955,270. Retractive switches. K. MAECKER Oct. 25, 1960 [Oct. 26, 1959], No. 36608/60. Heading H2B. A limit switch has a contact-carrying rocker which is always in contact with a permanent magnet by way of a tilting edge which forms a pivot for the rocker which has a foot operable by abutments of an actuator. The rocker 4 is T-shaped and carries a steel insert co-operating with the magnet 1. As shown, the rocker has a central ridge forming the tilting edge, but this ridge may be formed on the magnet (Fig. 4, not shown). The rocker carries bridging contacts 11, 12, co-operating with fixed contacts 15, 16 and is supported, in case of magnet failure, by springs 19. The actuator 6 bears on the foot 4b through springs 7, 13, and a return spring 9 is provided. The actuator 6 may be extended to the right to act on a further normally-open or normally-closed contact lever (Figs. 5 to 8, not shown).
