Abstract (en)

[origin: EP1372172A1] A pressure gas switch (30) has two switch pieces (1,2), with a switching stretch between them when it is switched off. An insulating material jet (5) is at the switching stretch, together with an adjacent gas storage zone (3), linked to the switching stretch through the jet channel (7). An intermediate wall (10) is within the gas storage zone, bonded to the jet and preferably as a one-piece unit.
