Abstract

474,920. Snap-action switches. CRABTREE & CO., Ltd., J. A. (Schiele & Bruchsaler- Industriewerke Akt.-Ges.) May 13, 1936, No. 13497. [Class 38 (v)] A snap - action switch comprises a pair of U-shaped contact arms 10a, 10b fulcrumed between clamped insulating members 4a, 4b formed with V- shaped clearance channels m. A tension spring 12 is connected between the ends of the contact arms and causes contacts 11a, 11b to snap between fixed contacts 9a, 9b and stops 13a, 13b when the members 4a, 4b are moved up and down either by a diaphragm 2 acting against control springs 5, 6 or by manual means. Specification 474,919 is referred to.
