Abstract

701,822. Tumbler switches; contacts; actuation of switches. ARNOLD, C. L., DOWSETT, R. W., SHARMAN. A. V., and M.K. ELECTRIC, Ltd. July 16, 1952 [July 18, 1951], No. 17016/51. Class 38(5) In a switch with a resilient contact blade 11 urged by a separate spring 14 into engagement with a fixed contact 9, and separated from it by the action of a cam 3 on a dolly, the blade is curled into part-cylindrical form at the hinge end 12, which is held compressed in a socket constituted by a recess in the switch housing 13 and a rigid conducting element 8, the arrangement being that in addition to the normal bending of the blade in operation it can slide bodily in the recess, so minimizing risk of fracture of the blade. The blade 11 is actuated through the intermediary of a roller 4 freely disposed in an aperture defined by turneddown ears 7 of a blade 5 which, together with element 8 is firmly secured to the terminal 6, and holds the dolly in the " on " position.
