Abstract: A probe pin (100, 100?) for electronic testing of semi-conductor elements is provided. The pin contains an electrically conductive core element (200) made up of a metallic alloy, and an electrically insulating jacket element (300) which surrounds the core element (200) over regions thereof. The core element (200) contains a distal contact section (210) for electrical contacting to a semi-conductor element. The metallic alloy of the core element contains at least 67% by weight rhodium, 0.1% by weight to 1% by weight zirconium, up to 1% by weight yttrium, and up to 1% by weight cerium. A method for producing a probe pin is also described.

Abstract: A spring contact for a sliding contact is provided having a terminal region and at least one contact region including an elongated spring element and a precious metal. The spring contact includes a conductive spring support and at least one contact piece. The spring support has essentially symmetrical rigidity in some regions in a plane perpendicular to the elongated extension of the spring support, and is made of a conductive material essentially free of precious metal. The contact piece(s) is/are conductively connected to the spring support, and has at least one surface to form the sliding contact. A surface of the contact piece(s) is made of a precious metal or a precious metal alloy. A slip ring transmitter for a motor or dynamo is also provided having a spring contact of this type, wherein the surface of the contact piece(s) touch(es) against the slip ring(s) in a conductive manner.

Abstract: A sliding contact has a base structure made from a wire, on whose one end a sliding contact structure is arranged. The sliding contact structure may be on the end face or on a lateral surface of the wire. The siding contact structure may be in a form of a sphere, a wire segment, or a trough-shaped member, for example. One or both of the base structure and the sliding contact structure may be angled or bent.
