Abstract

189,307. Hall, J., and New Switchgear Construction Co., Ltd. Oct. 17, 1921. Switches, quick-action. - In switches having quick make-and-break mechanism mounted on a hinged interlocked lid, a longitudinally movable member W carrying the switch contacts X and attached to a plunger f is operated by a lever m pivoted to a link n and itself acted upon, with lost motion, by a pivoted handle p. The quick action is secured by compression springs 12 enclosed in tubes 6, operating between knife edges or like abutments 4, 5, which work in holes Z, 2. As shown in Fig. 1, the closing of the switch releases a spring-pressed catch 7 which locks the lid.
