Abstract
444,444. Tumbler switches. BAIN, R., 25, Beaudesert Road, Handsworth, Birming- ham, and ALLDAY, N., The Nest, Streetly Lane, Four Oaks, both in Warwickshire. April 30, 1935, No. 12828. [Class 38 (v)] A tumbler switch has a dolly 9 pivoted at 12 to the bridge 7 and has a contact member 18 pivoted at an intermediate point (not shown), on the dolly. A link 22 slidably engages a hole in a boss 21 on the contact member, the other forked end 23 of the link being fulcrumed to the bridge at 24. A compression spring 25 providing a snap-action. A curved plate 27 on the contact member engages the underside of the bridge, and by its camming action converts into pivotal movement the initial longitudinal movement of the contact member due to the displacement of its pivot by movement of the dolly. In a modification, this action is produced by a rib on the base, engaging a flange on the contact member. Specification 443,748 is referred to.
