In-die Riveting Silver Contacts

In-die Riveting Silver Contacts adopt automated in‑mold riveting with high‑purity silver material. They deliver low contact resistance, high voltage tolerance, and arc‑resistance, rated for- 40 °C to 125 °C. Optimized material matching and real‑time process monitoring secure batch consistency for high‑frequency, high‑current electronic connection scenarios.

In-die Riveting Silver Contacts remove common defects from traditional secondary offline riveting, such as loose rivets and misaligned contact tips, which raise production costs via repeated material handling. Our automated parts integrate high-precision brass strip progressive stamping with inline silver rivet feeding and cold-heading staking in a single press stroke. As a direct wholesale manufacturer based in China, we deliver custom-engineered stationary terminal assemblies designed specifically for wall switches and electromechanical relays. These components ensure optimal mechanical retention, low electrical contact resistance, and consistent batch performance for demanding high-frequency switching applications.

Process & Quality Control of Electrical Contact Assemblies

Silver-rivet raw-material screening

Incoming silver wire and alloy strips undergo spectrometer chemical composition analysis to verify noble metal content. Density and grain structure checks ensure uniform arc erosion resistance during heavy load operations.

In-die staking concentricity control

Our progressive tooling incorporates real-time optical sensors to monitor rivet positioning. The mechanical staking force is precisely calibrated to lock the silver tip into the brass carrier without micro-cracking.

Shear-strength & electrical batch testing

Every production run is sampled for push-out shear force and electrical contact resistance. Destructive mechanical testing guarantees that the rivet-to-substrate bonding exceeds industrial benchmarks.

Surface passivation & burr removal

Finished stamped terminals undergo ultrasonic degreasing and chemical passivation. This removes residual stamping oils, prevents surface oxidation, and ensures clean solderable or plug-in connection points.

Typical Application Scenarios of Switch Terminal Accessories Brass Stamping

01/

Electromechanical Power Relays

The assembly can serve as a fixed contact terminal inside electromechanical power relays, where the silver contact provides the switching interface and the brass stamping provides the terminal structure and mounting features.

02/

Household Wall Switch Mechanisms

Wall switches require compact fixed-contact components that can be positioned accurately within the switching mechanism. The silver-contact/brass-terminal structure is suitable for fixed electrical contact assemblies integrated with stamped mounting features.

03/

Small-Capacity Contactors

For compact contactors within the specified electrical range, the riveted silver contact can be integrated with a stamped brass terminal when the contact geometry, terminal structure, and mechanical joining requirements are defined by the product drawing.

04/

Home Appliance Control Relays

Home appliance control relays used in equipment such as control panels, household electrical modules, and appliance switching circuits can use fixed silver-contact terminals where the terminal profile and contact position must match the relay mechanism.
