Abstract
370,945. Snap-action switches. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Dec. 3, 1930, No. 27563/31. Divided on 368,338. [Class 38 (v).] An ironclad switch having the spring toggle mechanism a, a<2> contained i n a housing d of the kind described in Specification 368,338, has a lost-motion connection between the handle h and the operating spindle c, and also between the operating spindle and an oscillating lever g which transmits the drive to a parallel-motion contact-arm suspension of the kind described in Specification 346,502. The operating spindle c has a rounded end c<2> on which is journalled the handle h, and has a key rib c<1> which engages a spider plate h<1> having a lost-motion connection with a shouldered recess in the handle h. The spindle c drives without lost-motion the toggle rocker arms a<2> but has a lost-motion connection with the arm g formed by the engagement of the key c<1> with a suitably-shaped hole. An auxiliary coil spring i is connected between the rocker arms a<2> and an abutment on the lever g, to retain the switch in the open position. Specifications 321,416, 321,428, and 327,632, [all in Class 38 (v), Electric switches &c.], are also referred to.
