Abstract
917,590. Mechanical switches, without quick action. SIEMENS & HALSKE A.G. Sept. 2, 1960 [Sept. 2, 1959], No. 30338/60. Class 38 (5). A rotary switch has an M-shaped compression spring 1 whose outer legs are pressed by a disc 2 against a central member 3 rotatable with the switch spindle, and whose inner legs are bent at 4 so that their junction engages a wedge-shaped recess 5 in an insulating member 6 carrying a contact bridging fixed contacts 7, 8, the shape of the recess 5 allowing slight rocking of member 6 during its movement, which is effected by its engagement with areas 9 on the outer legs of the spring 1. The contact 8 may comprise an endless loop pick-up ring or part of a multi-element pick-up ring, provided with a number of contacts 7. Composite compression spring members may be used to provide between two and eight M-shaped springs, as desired, Figs. 4 to 7 (not shown).
