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.
