FIELD: manufacturing technology.
SUBSTANCE: invention relates to electric switching device (10), in particular for electric switching system with gas insulation. Switching device (10) comprises two cavities (41, 42), in which first conductive element (26) is installed and, if necessary, other switching device (10) components. Further, provision is made for support insulator (20), which separates two cavities (41, 42) from each other and through which first conductive element (26) passes through so, that enables movement of first conductive element (26) in ring (24), wherein ring (24) is gas-tight connected with support insulator (20), wherein between first electrically conductive element (26) and ring (24) there is at least one o-ring (28).
EFFECT: invention enables possibility of switching device with gas insulation operation with gas under pressure.
