kontaktspetsen

Kontaktspetsen is a term used in Nordic languages, particularly Swedish and Norwegian, translating to "the contact tip" or "the tip of a contact." In technical contexts it refers to the pointed or rounded portion of a conductor, probe, or connector that establishes electrical contact with another surface or receptacle. The term appears in manuals, product specifications, and lab protocols describing probes, test leads, and related equipment.

In instrumentation, kontaktspetsen denotes the exposed conductive tip of a probe or electrode, designed to create a reliable electrical connection with minimal contact resistance and mechanical wear. Variants include sharp tips for high-resolution measurements and blunt tips for safer contact with delicate surfaces. Tip materials commonly include copper, brass, tungsten, or gold-plated finishes, chosen for conductivity, durability, and corrosion resistance. Some probes use detachable or interchangeable tips to accommodate different measurement ranges or safety requirements.

Design considerations for kontaktspetsen focus on achieving consistent contact quality, minimizing impedance, and reducing damage to tested surfaces. The geometry and coating of the tip influence measurement accuracy, insulation integrity, and user safety. Handling and maintenance—keeping tips clean and free from oxidation—are important, especially when working with high voltages or sensitive electronics.

Etymology and usage: the word combines kontakt (contact) with spetsen (the tip) in Swedish and Norwegian, reflecting its role as the contact point on measuring and testing equipment. Related terms include probe tip, needle electrode, and test probe.
