Abstract
1,230,820. Snap-action switches; hand actuating devices for switches. CARR FASTENER CO. Ltd. 4 July, 1969 [26 Aug., 1968], No. 40706/68. Heading H1N. An electrical switch comprises a casing 1 housing fixed contact 10 and movable contact 12 and having a pivoted actuating member 16 which is rockable into opposite operative positions under the assistance of snap spring 11, 13, 14, actuating member 16 being pivotally supported by lugs 17 projecting laterally from opposite sides of actuating member 16 and respectively rotatable in apertures in opposed side walls of casing 1, each lug 17 being shaped at one part of its periphery to provide line contact with the wall of the aperture, the part being offset with respect to a plane containing the transverse centre line of the actuating member 16. The line contact parts act as fulcrums and increase the snapping action. Resilient arms 22, 23 mount the switch in an aperture in a support.
