Abstract

667,690. Snap-action switches. LUNDBERG & SONS, Ltd., A. P. June 5, 1950. [June 11, 1949] No. 15588/49. Class 38 (v). The switch-operating lever 23 is pivoted at 24 and has a bore 26 housing a spring-pressed ball 30 movable over the peak of a fixed cam 28 so as to provide a snap action, a shoulder 25 on the lever 23 being arranged to push a movable contact 22 into engagement with a fixed contact 20. The lever may act on a pair of contacts in each extreme position, and may act simultaneously or successively on two pairs at one end of the switch. The cover 17 is retained in position by a spring clip 14 which engages in a recess 16 in the cover.
