Contact Springs

Accurate conductivity, always

Our canted coil spring ensure electrical contact to manage high, medium and low current over long periods

RPK Group contact springs are used to manage more power in less space at cooler running temperatures. Our contact springs, which serve as multiple contact points for optimal conducting or grounding capability in static or dynamic electrical applications, ensure consistent, reliable connections, even under shock and vibration.

Many design factors, including spring force, wire material, wire diameter, coil height, and plating thickness, contribute to the performance of the canted coil spring. Our engineering team designs these canted coil springs that are not just perfect for managing power, but also for mechanical retention due to their constant force curve and for electromagnetic shielding.

Advantages and benefits of contact springs

  • Our contact springs work in static or dynamic electrical applications. We assure reliable connections even under shock and vibration
  • Plating can make contact springs more efficient in humid or corrosive environments, or in any application that calls for higher conductivity
  • High-precision with laser-welded spring ends


  • Wire diameter: 0.10-2 mm (0.004-0.08 in)
  • Other dimensions as required


The choice of the right material, surface treatment and coating are critical for the final quality and safety of the product. From stainless steels to the most specific materials bought in from the best suppliers.
