APPLICATIONS

Precision springs for electronics

Micro springs, pressings,  stampings, and gas springs power today’s electronics. They appear in low, medium, and high volumes. From early prototypes to full production runs, size, stability, and repeatable force always matter.

Our products are built into everyday and industrial electronics. Examples include compression springs for battery contacts and latches. Torsion springs handle hinge control, while electrical contact springs support connectors.

Wire forms guide cables, flat pressings provide shielding, and bent parts serve as clips and retainers. Gas springs complete the range with smooth, adjustable access to panels.
