Abstract

744,181. Thermal switches. BENFORD, P. R. April 26, 1954 [April 24, 1953], No. 11335/53. Adition to 663,368/33 [Group XI]. Class 38(5) [Also in Group XI] The switch of the parent Specification is modified by the replacement of the bimetalic strip by an expansible chamber, e.g. a metal bellows 11 or a flexible diaphragm capsule. The chamber actuates a snap-action mechanism of the kind described in Specification 657,407.
