Abstract (en)
[origin: EP1580783A1] The device has an auxiliary shaft (4) for permitting handling of a movable contact (5) of a vacuum switch (1) during movement of a main shaft (2). The shaft (4) crosses a wall (7A), of a case (7), that separates volume of isolating gaseous fluid (G 2) from another volume of blanket gas (G 1) at lower pressure. Difference between pressures of the fluid and the gas causes differential pressure force that is applied on the shaft (4). The differential pressure force is provided for assuring contact pressure force to hold the contact (5) against another contact (6).
