Abstract
520,482. Tumbler switches: TUCKER & CO., Ltd., J. H., and FUKE, F. C. Oct. 20, 1938, No. 30295. [Class 38 (v)] In a tumbler- or other switch h particularly adapted for use with A.C. the moving contact or contacts 10 are carried on a bowed spring 9 and operated by applying a force to the spring near a contact. In the form shown, a dolly; pivoted at 14a, has a forked end which drives a rocker 13 pivoted at 13a and the rocker engages either above or below the spring to move it across its centre line. A spring 15 maintains the dolly in its two alternative positions. The invention is applicable to a double pole switch, Fig. 4-6 (not shown) or to a twoway switch.
