Abstract

401,939. Tumbler switches. BAIN, R., 25, Beaudesert Road, Handsworth, Birming- ham, and ALLDAY, N., The Nest, Streetly Lane, Four Oaks, Warwickshire. March 10, 1933, No. 7272. [Class 38 (v).] A tumbler switch has a movable contact bridge 15 of the form shown in Fig. 3 pivoted on a pin 29 and movable in a plane parallel to the plane of the base. The contact bridge 15 is operated by a tumbler 16 through the medium of a telescopic link having a deadcentre compression spring 42. Sparking between the fixed contacts 14 and the operating mechanism is reduced by the provision of an upstanding wall 43 which encloses the operating mechanism. Further projections 48, 49 prevent sparking on to the fixing screws 47. Specification 398,322 is referred to.
