Abstract

1,218,358. Retractive switches. MIDLAND ELECTRIC MFG. CO. Ltd. 11 April, 1968 [26 April, 1967], No. 19237/67. Heading H1N. In an electric switch of the type comprising a housing 10 containing a switch 12 with an actuator 13 and operating means 17 for the switch mechanism incorporating an operating element 20, the operating means 17 incorporates a body 18 which carries the operating element 20 and a captive screw-threaded element 24 coacting with a complementary screw-threaded portion 14 of the housing 10 disposed about an opening 15 for the operating element 20. Spring-loaded element 20 is depressed by a can surface 21a on spindle 21 carrying arm 22 and roller 23. Element 24 is held captive on body 18 by circlip 25. The lower part 26 of body 18 is octagonal in cross-section and mates with an octagonal recess in body 10 or may have two diametrically opposite projections mating with diametral slots in the recess, Fig. 3 (not shown). The operating means may be a push-button (not shown) or a roller mounted directly on a plunger (not shown).
