Products Description
Pure Copper Electrical Contact Rivets are one-piece cold-formed fasteners made of highly conductive copper, designed for use as moving or stationary contacts in low- to medium-current switching devices. These rivets are directly mounted to contact bridges or terminals via a riveting process, forming a one-piece copper contact interface without the need for silver alloy inlays or overlays. They are widely used in cost-critical applications such as wall switches, microswitches, general-purpose relays, and automotive auxiliary circuits, where electrical loads are moderate and environmental corrosion risks are manageable.

Technical Advantages
Functional Plating Compatibility
Three surface treatments precisely match different environments: nickel plating for oxidation and corrosion resistance, silver plating for resistance reduction and arc resistance, and electroless plating for economical and practical use, adapting to diverse needs in various scenarios for Copper Contact Components.
High-Efficiency Thermal Buffer And Durability
Copper-based high thermal conductivity rapidly dissipates arc heat, reducing contact surface erosion; the plating strengthens surface protection, extending One-piece Solid Copper Contacts service life, suitable for low-to-medium frequency on/off cycles.
Frequently Asked Questions
Why are copper contacts more advantageous than silver contacts in low-to-mid-range applications?
Electric Copper Contacts, through surface silver/nickel plating processes, retain the high conductivity of the copper substrate while controlling overall costs, making them particularly suitable for high-volume procurement scenarios sensitive to initial investment.
How to choose between nickel-plated and silver-plated in practical applications?
Nickel-plated Solid Contact for Switch Parts are suitable for humid or corrosive environments, extending lifespan through sacrificial anodic protection; silver-plated are suitable for high-frequency switching scenarios, their low contact resistance reducing signal delay, but the risk of silver migration must be considered.
How to ensure the long-term reliability of copper contacts?
Guaranteed through a triple quality control system: raw material spectral detection, process control, and accelerated life testing of finished products. All Copper Switch Contacts undergo mechanical life testing and temperature rise testing to ensure a temperature rise ≤35K at rated current.
