Abstract

1,132,879. Fluid actuation of switches. CONTROLS CO. OF AMERICA. 3 Oct., 1966 [22 Oct., 1965], No. 44019/66. Heading H1N. In a switch similar to that of Specification 884,686, the diaphragm 14 is formed with hollow lugs 54 which in the " reset " position, abut the casing to limit relaxation of a spring 26. Reference has been directed by the Comptroller to Specification 884,686.
