Product Description
Precision Stamped Spring Contacts – Phosphor Bronze for Connectors & Switches
Tingfeng Hardware provides precision stamped spring contacts using phosphor bronze and beryllium copper materials specifically for connector and switch applications. Our spring contacts achieve stable elastic force and low contact resistance through precision progressive die stamping and stress relief heat treatment. With 16 years of precision manufacturing experience, we provide high-reliability spring contact solutions for switches, connectors, and relays.
Product Description
Spring contacts are core components for switching control and signal transmission in switches and connectors. Our phosphor bronze spring contacts achieve precise contact surface geometries and stable elastic force through precision stamping forming. Phosphor bronze offers excellent conductivity (approximately 15% IACS), fatigue resistance, and elastic memory, suitable for high-frequency switching operations and long-term use. Silver or gold plating controls contact resistance below 20mΩ while ensuring oxidation and corrosion resistance. Each spring contact undergoes 100% force testing and dimensional inspection, suitable for micro switches, tactile switches, relays, and connectors.
