Abstract: The present invention relates to an electrical contact element (1), that has a plurality of contact areas (21, 22), with a base body (6) made from a first material and a coating (7) applied to the base body (6) made from a coating material. In at least one area of the base body (6) within at least one contact area (21, 22) in each case the first material is removed and is at least partially replaced by a second material. The second material and the coating material each have a higher electrical conductivity than the first material.

Abstract: A contact pin (100; 10012, 10032) for electrically connecting a first electrical contact area (13), which is arranged on a device under test (300) to be surveyed, and a second electrical contact area (17), which is arranged in a test base (200; 200?), has an elongate central region (1) which is mechanically connected to the test base (200; 200?), has a first spring arm (21), the first end (41) of which is connected to a first end (5) of the central region (1) and the second end (111) of which has a first contact region (12) for electrical contact-connection to the first electrical contact area (13), and has a second spring arm (31), the first end (61) of which is connected to a first or second end (5, 7) of the central region (1) and the second end (151) of which has a second contact region (16) for electrical contact-connection to the second electrical contact area (17).
