Abstract

657,263. Tumbler switches. D. S. PLUGS, Ltd., and LUND, J. Jan. 29, 1949, No. 2516. [Class 38(v)] A switch comprises a recessed insulating base 5 in which is a projection 8 on which is mounted a compression spring 12 carrying a metal thimble 13 movable by the dolly arm 18 to engage beneath a pair of fixed contacts 10 and complete the circuit. The dolly pivots 15 are maintained in their seats in the extremities of arms 14 on the base 5 by a metal cover plate 19, secured by rivets 19a, which may also serve for mounting the switch through holes 19c. An insulating cover 20 surmounts the central portion of the cover 19. Additional fixed contacts may be provided for a 2-hole switch and a number of switches may be mounted together and operated by a common dolly.
