Abstract
425,424. Snap - action switches. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Nov. 11, 1933, Nos. 31435/33 and 19357/34. [Class 38 (v)] In a snap-action toggle switch with positive actuation of the general kind shown in Specifications 140,180, [Class 38 (v)], 378,433, and 384,323, the spring-carrying link has rigidly embodied in it one or more positive-action levers c<3> which co-operate with fixed abutments f<1>, f<2> and which are situated laterally with respect to the plane of movement of the spring d so that the position and movement of the spring d are not interfered with. In the form shown, the compression spring d is arranged round one limb c<2> of a member c which is pivoted to the contact arm b at c<1> and the limb c<2> passes through a hole in a member e on the dolly a. Side limbs c<3>, c<4> on the member c constitute the positive-action levers which engage the abutments f<1>, f<2>. In modifications, the limbs c<3>, c<4> pass through holes in the member e, or there may be only one limb c<3> or c<4>, or there may be one limb on the member c and another on the member e.
