Abstract
780,972. Snap-action switches. CUTLERHAMMER, Inc. Dec. 10, 1953 [Dec. 12, 1952], No. 34407/53. Class 38 (5). A lever-operated switch comprises a pair of stationary contacts mounted in opposite walls of the base, and a co-operating bridging contact arranged to slide over the walls and the station - ary contacts with a snap action. A casing 10 has a central recess 11 and fixed contacts 14 and 15 are mounted on the walls thereof and protrude partly into recesses 12, 13, the ends of the contacts being bevelled as at 14a so that the ends 16a, 16b of the bridging contact 16 can slide easily. A carrier member 17 supports the contact 16 and is pivoted at 17b, 17c, a spring 20 being compressed between a cross-member of the carrier and an extension 22 of the operating lever 23. The upper ends of contacts 14 and 15 are located in apertures in an insulating coverplate 28 and are separated from a metal coverplate 26 by an insulating plate 27.
