Contact springs: Perfect in conductive function
Contact springs are specialized spring components that are used in electrical and electronic applications. They ensure a reliable electrical connection between two components and compensate for mechanical tolerances. Contact springs are usually made of conductive material, such as gold-plated copper, bronze or spring steel with coatings to ensure optimum electrical conductivity and corrosion resistance.
We develop and manufacture contact springs that meet your exact requirements - from batch size 1 to large-scale production, transforming your products into smart components, assemblies and devices.
Contact springs: At home in many industries
Our contact springs are used worldwide in the following industries, among others:

- Wire diameter 0.03 - 3.00 mm
Versions
- Compression, tension and torsion springs, wire and stamped-bent parts as well as spring washers
Surfaces
- Optimum contacting and conductivity thanks to surfaces: Ni, Cu, Ag, Au, passivation (organic and metallic)
Special features
- Adhesion testing of surfaces (e.g. temperature test or tensile tests)
- Resistance measurements
- For compression springs, 100% length test with sorting and control on the machine
- For tension springs, 100% force and camera geometry test with sorting and control on the machine
- Position test of the legs using laser, sensor, camera
