ABSTRACT A contact arrangement is provided for a medium- or high- voltage switch including two contact surfaces that are generally parallel and relatively movable via a predetermined path between open and closed positions. During closing, the two contact surfaces define predetermined areas of relative engagement between the two contact surfaces. The move- ment along the predetermined path during contact engagement generally defines a first direction. The two contact surfaces are arranged relative to each other and the first direction such that, during closing, the relative engagement between the two contact surfaces defines a locus along each contact surface that is non-parallel to the first direction.
