Abstract
435,537. Oil-break switches. SCARPA, G., 5, Via Fiume, Savona, Italy. Dec. 21,1933, No. 36047. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 23, 1934]. [Class 38 (v)] In an oil-break switch, the pressure due to the arc formed on separating the contacts a, c forces oil from a casing e through a conduit g and across the flow of vapours issuing from the aperture f through which the movable contact c is withdrawn from the casing. The movable contacts may be carried by a support adapted to rotate on its own axis to bring the movable contacts into and out of engagement with the fixed contacts.
