Abstract

140,182. Crabtree, J. A. Feb. 20, 1919. Snap-action switches; contacts. -In an intermediate switch, the contacts are so arranged as to facilitate the introduction of quickaction mechanism, which may be of the dead-centre type described in Specifications 140,179 and 140,180. The movable contact member carries two circuit-closing members 52, 53 illustrated diagrammatically in Figs. 1 and 2, each coupling together two fixed contacts 49, 51 and 48, 50 occurring on the same side of the movable contact member, and a third circuit-closing member 54 connecting together two contact surfaces 48, 49 on opposite sides of the movable contact member. In addition, in the position shown in Fig. 2, the circuit-closing members engage a fixed non- circuit terminal 55 or two terminals connected together so as to connect the contacts 50, 51. A tumbler switch constructed in accordance with the invention is shown in Fig. 5. The space between the lateral circuit-closing members is free from cross-connexions and facilitates the mounting of the quiclc-action mechanism and of an insulating and separating partition.
