Abstract

460,738. Actuation of switches. RAUWERS, A. E., and VOISIN, P. E. Jan. 14, 1936, No. 1218. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 29, 1936.] [Class 38 (v)] A pressure-operated switch comprises a rigid container 1 carrying inside it a bellows 2 thus forming between them a chamber 3 containing oil. When a fluid under pressure enters through a pipe 11 the bellows collapses against the action of an adjustable spring 8 and a circuit is broken sparklessly under the oil at contacts 4, 5.
