Abstract

613,418. Snap -action switches. CRAIG, H. G., and ROWE & CO., PROPRIETARY, Ltd., H. Feb. 12, 1945, No. 3515. [Class 38 (v)] A multipole switch comprises pairs of opposed movable contact members 9 bridging pairs of fixed contacts 7 and actuated by cams 16. The cams 16 are secured to a cam-shaft 4 which is driven by a knob 26 with a lost-motion pin-and-slot connection 19, 18. A coiled spring 22 connects the pin 19 to a rivet 23 secured to the cam-shaft 4 and assists contact-biassing springs 12 in producing a snap-action. Inserts 8 in the switch body locate the fixed contacts and terminals 13 and serve to arrest the cams in their end positions. Graphite-impregnated moulded disc-bearings 6 form dust-proof seals for the body of the switch. In a modification (not illustrated), the different pairs of opposed contact members are arranged on different diametrical lines. Specification 514,202 is referred to.
