Abstract

530,124. Tumbler switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., and HARRISON, B. G. June 14, 1939, No. 17349. [Class 38 (v)] In a tumbler switch for A.C. circuits, the moving contact member, Fig. 5, comprises insulating plates a with contact strips e arranged between them and secured together by a rivet or projection h which is engaged by a pin i on the dolly so as to tilt the contact member. The pin i is biassed by a spring and moves in fixed slots o so as to provide a snap action for the dolly. The projection h may be cam-shaped as shown in which case the contacts e are both in engagement with their fixed contacts in the " on " position shown. In a modification, Figs. 6, 7 (not shown), the projection h is rectangular and there is one central supporting spring s for the movable contact member which assumes a tilted position in each of the two positions of the dolly.
