Abstract
409,232. Tumbler switches. BAIN, R., 25, Beaudesert Road, Handsworth, Birming- ham, and ALLDAY, N., The Nest, Streetly Lane, Four Oaks, both in Warwickshire. Nov. 13, 1933, No. 31529. [Class 38 (v).] In a tumbler switch of the kind described in Specification 398,322 in which a contact arm moves in a plane parallel to the base and is operated by a dolly moving in a plane at right angles to the base through the medium of a spring toggle link, projections are provided on a fixed part of the switch against which the link is adapted to lever to give a positive drive to the contact arm. The contact arm 20 is pivoted at 22 and is actuated by a dolly 30 through a spring toggle link comprising a tubular part 31 having a spherical end 32 bearing on the contact arm, and a forked rod 28 engaging the dolly and slidable in the tube 31. A compression spring 34 has its ends accommodated in recesses in the part 32 and in a sleeve 35 on the rod 28. When the dolly is moved to actuate the switch, the sleeve 35 moves to engage one of a pair of projections 37 depending from the bridge piece 17 on which the mechanism is mounted, and moves the contact arm positively until the spring has passed deadcentre.
