Abstract
426,598. Tumbler switches. COOK, F. L., 42, Mollison Street, Abbotsford, Victoria, Australia. Aug. 28, 1934, No. 24815. Addition to 425,799 and 426,597. [Class 38 (v)] A tumbler switch having a spring mechanism of the kind described in the parent Specifications, comprises a dolly 1 pivoted by means of trunnions 4 on its depending legs 2 on which are fulcrumed the legs of a U-shaped contact bridger 9. A U-shaped spring 6 with divergent limbs is fastened by a ring 7 to the rocker 9 and its limbs pass through an aperture in the bridge 5. When the dolly is moved over, the bridger 9 is forced downwards and the spring 6 has its arms flexed towards one another by reaction with the aperture in the bridge, so that when the fulcrum of the bridger crosses the line of the spring the bridger is snapped over. In a modification, Fig. 6, the contact bridger 9 and the dolly 1 have a common pivot 12, and the arms of the spring 6 are flexed by an aperture 8 in an inner part 11 of the dolly.
