Beryllium Copper Stamped Contacts for Automotive Door & Window Switches
Tingfeng Hardware provides beryllium copper stamped contacts specifically for automotive door and window switches, manufactured from beryllium copper C17200 through precision stamping and stress relief heat treatment processes. The contacts offer ultra-high durability (≥1M cycles), meeting the stringent requirements of automotive switches for operating feel and contact reliability.
Product Overview
Automotive door and window switches are high-frequency interior control components, requiring core spring contacts to withstand dozens of daily operations while maintaining force stability and contact reliability over millions of cycles. Our beryllium copper contacts are formed through precision progressive die stamping, achieving precise force-displacement characteristics; stress relief heat treatment eliminates stamping internal stress, ensuring force decay <15% after 1 million operations.
Beryllium copper's excellent elasticity and fatigue resistance maintain stable rebound and contact force under high-frequency operation. Each contact undergoes 100% force testing and dimensional inspection, suitable for driver door switch assemblies, window lift switches, sunroof control switches, and other automotive interior applications.
