Abstract

547,705. Gas-blast switches. AKT.-GES. BROWN, BOVERI & CIE. Feb. 1, 1941, No. 1341. Convention date, Jan. 22, 1940. Addition to 494,044. [Class 38 (v)] In order better to rupture the arc between the auxiliary contact and hollow contact of a switch according to the parent Specification, the hollow contact b is extended into the exhaust chamber m past the tip of the auxiliary electrode e and has an aperture o for the blast-gas to get outside the contact b and surround the arc between b, e, on all sides.
