A switching device comprises two contact members (2, 3) at least one of which is movable such that they are movable relative to and from each other between a first position in which they are in electric contact with each other, and second position in which they are separated and have different potentials. It also comprises at least one insulating body (1) which electrically insulates the contact members (2, 3) from each other when they are in the second position. The insulating body (1) is arranged such that a main part of an electric field between said contact members (2, 3) is located within said insulating body (1). |
