Contact Springs and Contact Parts

Reliable connectivity, always

Stamped and multislide metal parts, plated contacts, and springs engineered for consistent conductivity in high-performance electronic systems.

RPK Group’s contact springs and parts are metal components dedicated to ensuring reliable electrical connectivity in your systems. Our product range extends from precision-stamped and multislide parts to spring contacts plated in gold, silver, or nickel—each engineered always to maintain conductivity. Typical applications include connectors in smart vehicles and advanced automotive systems (from ADAS to brake-by-wire), as well as data center hardware and other cutting-edge technologies.

For the most demanding conditions, we also provide canted coil springsthat maintain connectivity even in extreme environments. Each coil in a canted spring acts as a contact point, providing continuous electrical contact around its circumference.

Advantages and benefits of contact springs

  • Our contact springs and parts work in static or dynamic electrical applications, ensuring reliable connections even under shock and vibration.
  • Plating (gold, silver, nickel, etc.) makes these contact components more effective in humid or corrosive environments, or any application requiring higher conductivity.
  • High-precision manufacturing (with features such as laser-welded spring ends) ensures consistent quality and performance.

Measures

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