Abstract: The invention relates to a cylindrically shaped contact element arrangement for a three-position-switch in medium or high voltage gas insulated switchgears, which provides a disconnector switch and an earthing switch, which further consist of one movable conductor and three contacts, which are busbar contact, center contact and earth contact, with a cylindrical shaped contact element arrangement for connecting tube shaped contacts which are orientated in axial direction and with spring means for providing contact forces, and that the cylindrical shaped contact element arrangement consist of multiple identical contact elements, which are hold in cylindrical position by a support structure, according to the preamble of claim 1. In order to create a contact system with possibly low ohmic restistance, which is furthermore compact, the invention is, that spring means for providing the radially expanding contact forces, are located inside the cylindrical shape, represented by the contact elements arrangement.
