Abstract

368,338. Snap-action switches. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Dec. 3, 1930, No. 36402. [Class 38 (v).] The snap-action mechanism of an ironclad switch, consisting of a toggle link a, a compression spring a<1>, and a rocker arm a2, is mounted between a wall b<1> of the casing and a plate d secured to the casing by three bolts two of which el, e<2> serve as stops for the rocker arm a2. The operating spindle has a lost-motion connection with a lever g, which operates the contact suspension links f, f<1> comprising a parallel-motion linkage of the type described in Specification 346,502. Specifications 321,416 and 321,428, [both in Class 38 (v), Electric switches &c.], also are referred to.
