Abstract

551,021. Snap-action switches; switch-cases. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Sept. 11, 1941, No. 11646. [Class 38 (v)] Fixed and movable contacts 1, 2, 12 are mounted in strips clamped between the two parts A, B of a casing. Push buttons 31, 32 on the two parts are adapted to press on one side or the other of a swinging member 24 anchored at one end on the edge of a slot in the moving contact support and at the other engaged by the free end of an S-spring 20 to initiate an overcentre snap action. The casing may be made of a transparent plastic. The buttons may be operated thermostatically or electromagnetically.
