FIELD: electricity.
SUBSTANCE: electric switching device includes movable contact element (5) located inside and outside insulating housing (1) and insulated gas-tightly from it. For formation of gas-tight transition there provided is the first and the second sealing elements (12a, 13a) that are pressed in turn as axial sealing elements to insulating housing (1) with enveloping shoulders (12, 13) of contact element (5). Besides, there provided is the third sealing element (11) that seals contact element (5) in radial direction.
EFFECT: creation of inexpensive switching device the service life of which is increased owing to reducing the wear of the first and the second alternately acting sealing elements.
