A Copper-Coated Contact Spring is a precision-engineered spring made from high-strength steel or alloy base material and coated with conductive copper plating. This coating significantly enhances electrical conductivity, while the spring structure maintains consistent contact force, mechanical durability, and reliability over long cycles.
These springs are widely used in connectors, battery contacts, PCB grounding, shielding components, and modular electronic systems.
