More Information
Summary:A contact pin for a high-voltage and/or medium-voltage switch includes a contact tip of arc-erosion resistant material, a tubular support sleeve connected to the contact tip and a support core in the sleeve. The contact tip is in a forward region of the contact pin where arcs arise during use. The sleeve is in a rearward region of the contact pin, adjoining the forward region, where no arcs arise during use. A pipe contact includes an arc-erosion resistant annular contact and a support pipe connected to the annular contact. The annular contact is in a forward region of the pipe contact where arcs arise during use, and the support pipe is in a rearward region of the pipe contact, adjoining the forward region, where no arcs arise during use. Methods for producing a contact pin and a pipe contact are also provided.
