Abstract

685,569. Snap-action switches. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May, 17, 1951 [June 1, 1950], No. 13764/50. Class 38 (v) A dead-centre, snap-action switch having a compressed leafspring is operable by a control member movable along the direction of compression of the spring and arranged to bear on one side or the other of a rocker to move the spring over-centre. In one arrangement, Fig. 1, the spring 1 is fixed at its lower end, and engages a notch in a body part 2 at its other end, and carries the rocker 7. The control member comprises a push-button 9 urged outwardly by a spring 10 and carrying an inverted U- shaped spring 8, the legs of which co-operate alternately with the rocket on successive depressions of the button to move the spring 1 from one side to the other, thereby moving a contact arm 4 carried by the spring 1 into and out of engagement with spring contacts 5, 6, The button 9 is enclosed by a rubber cover 12 to render the switch damp-proof. In a modification, Fig. 3, the upper end of the spring 1 pivots in the rocker, which in turn pivots on the member 2, and the lower end pivots in a rocker 13 carrying a contact 14 end pivoted in a terminal member 15.
