Abstract: A low impedance, spring loaded electric connector which comprises a cylindrical body receiving a conductive wire, a plunger guided by the body and having a tip for electrically contacting with an external conductive surface, a spring compressed between the body and the plunger. The plunger can slide along the body, and is biased by the spring to assure reliable contact with the conductive surface. This connector, further, includes a resilient and conducting cantilever making sliding contact between the plunger and the body for establishing an electric path bypassing the spring. The cantilever may be formed as a portion of the plunger, or alternatively may be made as a separate one attached to the plunger or the body.
