A contact system for an electrical high-voltage apparatus or the like such as a high-voltage power circuit breaker or the like wherein a gaseous insulating medium is used includes a contact system having at least one contact piece. The contact piece includes an electrically conductive annular member having respective end portions. One of the end portions carries a graphite electrode having a nozzle-like configuration for conducting away the gases produced when the apparatus is switched to the open position. The contact piece is also provided with support member having a free end portion. The other end-portion of the annular member surrounds and engages the free end-portion of the support member to form a shrink-joint therewith and thereby establishes a good electrical connection between these members.
