Abstract

822,235. Tumbler switches. FALK, STADELMANN & CO. Ltd. April 23, 1957 [April 20, 1956], No. 12064/56. Class 38 (5). A pivoted dolly 6 has a recess 6a engaged by a bridging contact 7 which is supported by a guide plate 10 urged upwards by a spring 9. Normally, ears 6b of the dolly are separated from ears 10a on plate 10 so that initial movement of the dolly causes the contact 7 to slide down the fixed contacts 8. When ears 6b abut ears 10a the plate 10 and contact 7 are forced about pivot 12 and move across dead centre into the opposite position. Specification 822,236 is referred to.
