Abstract (en)

[origin: EP0696040A1] The switch has a pair of switch elements (1,2) displaced relative to one another within a switch chamber filled with an insulation gas, each having a network current contact (6,7) and an auxiliary contact (8,9). One of the switch elements (1) is acted on directly by the operating drive and has an attached jet (10) with a restriction (11) through which the compressed insulation gas is forced from a pressure space (12) and/or a compression space (19) to a buffer space (14). The end of the jet facing the other switch element supports a coaxial screening (21) enclosing the jet and forming part of the drive force coupling between the switch elements.
