Abstract

554,934. Snap-action switches. BRITISH MECHANICAL PRODUCTIONS. Ltd., and DEAKIN, S. T. Jan. 22, 1942, No. 951. [Class 38 (v)] A snap-action is obtained by moving a member transversely to its length, a spring acting along its length separating two movable parts, while two rocking levers have their inner ends pivoted on the moving parts, their outer ends being movable in same direction as the transverse member to operate as a toggle. In the example, contacts 7 and 8 are bridged. alternatively as a casing 16 snaps over under the action of two levers 18 pivoted at their outer ends in members 13, parts of a slider which can travel up or dawn. While their inner ends are pivoted in grooves in transverse members 14 held apart by a spring 15. In a modification the casing is not used, the two members 14 having co-acting telescoping parts over which the spring 15 fits.
