Abstract
657,434. Snap-action switches; thermal switches. TAYLOR, E. H. Feb. 7, 1949, No. 3330. [Class 38(v)] [Also in Groups XIII, XXII and XXXII] A snap-action actuating member buckled similarly to that of Specification 600,055 comprises a rectangular plate 1 of spring material or bimetal, Fig. 2, having a stamped-out tongue 2 carrying a contact 5 and stressed to draw the outer limbs 7 together by crimping the connecting bridge 6. The stress may alternatively or additionally be obtained by cruising or spreading the opposite plate end 9. Fig. 6 shows a triangular plate which may be crimped at 12 or spread at the root of the tongue 10. Alternatively, the plate may be semi-circular, Fig. 7 (not shown).
