Abstract

868,270. Thermal switches; fluid actuation of switches. BOSCH G.m.b.H., ROBERT. May 27, 1959 [June 4, 1958], No. 18013/59. Addition to 773,712. Drawings to Specification. Class 38 (5). The trifurcated snap-acting switch member of the parent Specification is replaced by a single flat spring strip slightly bowed to have a snap-action and inherently capable of returning to its original position when the actuating force is removed. The bell-crank lever is modified so as to act positively on the switch member in one direction only. An adjustable back stop is provided for setting the switch differential.
