Electric
Electrifying life for more than 50 years
For almost five decades, RPK Group has supplied electromechanical components to leading consumer-goods and industrial customers, from HVAC and home-automation devices to switchgear, connectors, and controls. We co-engineer contact springs, wire forms, stamped metal parts, and copper coils, plated in gold, silver, copper, or nickel to improve conductivity and resist corrosion across low-, medium-, and high-voltage applications. Precision forming and laser-welded spring ends maintain consistent contact performance throughout the product's life.
