Abstract

598,129. Snap-action switches. MARKS, S., and BOOTH, E. R. Aug. 30, 1945, No. 22381. [Class 38(v)] A selector-switch for radio receivers comprises an insulating-plate D carrying a plurality of contacts E, F in the form of the bared ends of insulated wires G, and a pair of pole-pieces El, F<1>, the contacts and pole-pieces being bridged by spring- blades N, N<1> carried by an insulating-plate K which is driven by a pinion M, and rack L and guided by the engagement of pins H in slots I. The various positions are located by a spring-pressed bell R engaging the pinion M.
