What is Copper Stamped for Switches?
Copper Stamped for Switches is designed for electrical connection points where a stamped terminal is combined with a silver contact by riveting. In relay static terminals, switch mechanisms, and contactor connection assemblies, the copper section provides the formed conductive path while the silver contact forms the switching interface. The manufacturing route covers copper material preparation, stamping, shaping, in-die staking, silver contact assembly, and final inspection. The existing product configuration uses a copper terminal with a riveted silver contact and is intended for switch, relay, and connector components. Production can follow customer drawings or approved samples, with the terminal profile, contact position, hole layout, and riveting structure defined before mass production.
Production Process of Custom Copper Stamping
Material Sourcing |
Raw copper and silver contact rivets are selected according to customer application requirements. Copper grades such as C1100 or C1020 are chosen for electrical conductivity and formability. Silver contact rivets use AgSnO2, AgNi, or AgCdO material grades to match specified load and arc resistance needs. |
Stamping and Shaping |
Copper coil stock is fed into progressive stamping tools. Piercing, bending, and blanking operations form the copper terminal profile. Dimensional tolerances are controlled per the part drawing for subsequent assembly. |
In-Die Staking |
In-die staking integrates silver contact rivets into stamped copper terminals within the progressive stamping die. The rivet shank expands inside the copper hole to form a mechanical lock. This method eliminates secondary manual riveting and maintains consistent rivet shear strength across production batches. |
Final Testing and Inspection |
Each component undergoes final testing, including electrical conductivity testing, dimensional checks, and mechanical stress tests. This ensures that all components meet the highest quality standards before being packaged for shipment. |
Typical Application Scenarios of Red Copper Stamping Parts
Automotive Power Relays
Integrated into 12V/24V DC switching relays and fuel pump control modules, handling high inrush currents without contact sticking or degradation.
Industrial Circuit Breakers
Deployed inside Miniature Circuit Breakers (MCB) and Molded Case Circuit Breakers (MCCB) as movable and stationary contact terminal bridges.
Smart Home Latching Relays
Optimized for zero-power-consumption smart meter relays requiring low contact bounce and stable low-resistance electrical pathways.
Industrial Automation Contactors
Utilized in heavy-duty electromechanical contactors managing motor startup loads and resistive heating circuits under continuous duty cycles.
Packaging and Transportation of Copper Contact Element
Packaging:
Copper‑stamped switch components are packed with dedicated anti‑collision and anti‑contamination materials. Individual separation is adopted to avoid surface scratches, metal debris, and oxidation during transit, keeping parts intact upon arrival.
Tracking and Transparency:
Multiple shipping solutions are available for domestic and overseas orders. We cooperate with verified logistics providers to balance lead time and freight cost according to project requirements.
Shipping:
Each consignment comes with a valid tracking number. Order transit status can be checked by customers for delivery schedule arrangement.
Commitment to Quality:
All copper stamped parts pass internal dimensional and appearance inspection before dispatch, complying with agreed drawing specifications before packaging and shipment.
