Abstract
An electrical switching device has a displaceable contact piece mounted on an encapsulated housing. The displaceable contact piece extends within and outside of the encapsulated housing. The displaceable contact piece is sealed gas-proof in relation to the encapsulated housing. For forming a gas-proof transition, first and second sealing elements are provided, which, as axial sealing elements, are alternately pressed against the encapsulated housing by peripheral collars of the displaceable contact piece. A third sealing element is provided for sealing the displaceable contact piece in a radial direction.
