Abstract

518,519. Snap-action switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., and HARRISON, B. G. Aug. 23, 1938, No. 24740. [Class 38 (v)] Snap-action in a switch is obtained by causing spring loaded balls d at each end of a bore or cylindrical part to ride over other balls f fixed in the casing. In the example, Fig. 1, a pivoted socket member a for a plug contact is provided, with such a snap action, on making and breaking contact between the plug sockets g and contacts h on the base. Specification 518,764, [Group XXXVI], is referred to.
