Abstract

172,658. Maschinenfabrik Oerlikon. Dec. 10, 1920, [Convention date]. Oil switches. - In oilbreak switches with resistance, the resistance 1 is carried by a submerged bell-shaped member 2, acting as a gas-collector. The gases are conducted outwards through the tube 4 of the sealing box. Within the member 2 is arranged the step contact 3 and the main contact 5, the resistance 1 being connected directly between them. Several contacts 3 may be provided, these being connected with different resistance stages.
