Kontaktpar

Kontaktpar, also written Kontaktpaar in German texts, is a term used mainly in German-language technical literature to denote a pair of elements that come into contact within a system. The meaning depends on context but generally refers to a dyad of contact points, surfaces, or nodes that interact functionally.

In electrical engineering and switch design, a contact pair describes the two conductive contacts that close or open a circuit. Such pairs are specified as normally open or normally closed and may be combined in multi-contact actuators.

In tribology and mechanical engineering, a contact pair refers to the two interacting surfaces (for example, a ball and a race, or a pin and a plate) where contact forces, friction, and wear are analyzed. The properties of the contact pair—pressure, lubrication, material hardness—determine performance and lifetime.

In network analysis or sociological contexts, if used, kontaktpar can describe a dyadic link between two nodes or individuals in a contact network. However, the term is less standard here; more common English terms are “dyad” or “edge.”

Origin and translations: Kontaktpar is formed from Kontakt and Paar. In English-language texts, “contact pair” is a direct translation but may not be a conventional label. The term remains specialized to German-language sources.
