Abstract

581,824. Snap-action switches. CHADWICK, R., and SMART & BROWN (ENGINEERS), Ltd. Feb. 2, 1945, No. 5703/44. [Class 38 (v)] [Also in Group XXXVI] A snap-action switch is operated by the rectilinear movement of a finger piece 10 which extends through a slot 11 in the switch casing and is rigidly connected to the movable contact member 1. The member 1 is acted upon by dead-centre snap mechanism such as is provided by the two links 6 co-operating with flat springs 9. In modifications coiled springs are used, or a spring on one side only of the contact members.
