Spring-loaded contacts are made of a contact body or barrel, a piston and an helical compression spring. The electrical contact is established by the pressure against a fixed, flat area called the pad connector.

Featuring particular advantages:

• contacts with a slant or polygonal piston. These designs lead to a radial force on the piston, resulting in a lower ohmic resistance.
• patented coaxial or in-line designs with integrated multifinger sliding contact (clip) establishing electrical continuity between body and piston.

The electrical multipoint connection between the mobile piston and the clip guarantees low, stable electrical resistance values without micro-discontinuities, even when the piston is moving or in case of vibrations, thus assuring maximum reliability.
