Why Choose Custom Silver Electrical Contacts According to Your Drawings in 2026
In 2026, most relay, contactor, switch, and circuit breaker manufacturers no longer accept off-the-shelf contacts. They need **custom silver electrical contacts according to drawings** to fit exact dimensions, meet specific performance requirements, and reduce assembly costs. At Chende, 70% of our orders are custom – from CAD drawings, samples, or even hand sketches.
Custom silver contacts allow you to specify alloy (AgNi, AgSnO2, AgW), head shape (flat, round, point), size (1–4 mm diameter), plating (gold/nickel), and base material (copper, copper alloy). This ensures perfect fit, better conductivity, longer life cycles, and RoHS compliance. Our low MOQ (10K pieces) and fast prototype (3–5 days) make custom orders affordable even for small/medium companies. For the full custom process, see our main guide Bimetal Rivets Ultimate Guide 2026.

Custom Silver Electrical Contacts Materials: What to Specify in Your Drawings
When sending drawings, specify the head material to match your application:
| Application | Recommended Head Material | Conductivity (% IACS) | Arc Erosion (mg/10K cycles) | Anti-Welding Force (N) | Why Choose This |
|---|---|---|---|---|---|
| Automotive Relays | AgNi20/Cu | 75–85 | 0.6–0.8 | 50–120 | Anti-material transfer in DC |
| EV Charging Relays | AgSnO2(12) + In₂O₃/Cu | 75–80 | 0.3–0.4 | 140–200 | High inductive load, RoHS |
| High Voltage Breakers | AgW50/Cu | 50–60 | 0.2–0.3 | 80–150 | Extreme arc resistance |
| DC Disconnect Switches | AgC5/Cu | 70–80 | 0.4–0.6 | 200+ | Superior anti-welding |
| Signal Relays | Pure Ag/Cu or Gold-plated | 100–105 | 1.5–2.0 | 20–40 | Low resistance, corrosion resistance |
Always specify head thickness (0.3–0.8 mm), shank diameter/length, and plating in drawings. Chende accepts DWG, DXF, STEP, PDF formats. For custom materials, see Bimetal Rivets Materials Comparison 2026.

Real Case: Custom Silver Contacts from Drawings for EV Charging Relay
A European EV charging manufacturer sent us CAD drawings for a 200A DC relay contact. They needed high anti-welding and RoHS compliance. We recommended AgSnO2(12) + 2% In₂O₃/Cu bimetal rivets with custom head shape. Key results:
- Anti-welding force reached 180 N
- Life cycles exceeded 300K in 800V DC tests
- Temperature rise 18% lower than their previous design
- Cost reduced by 35% vs solid silver
They approved the prototype in 4 days and ordered 1.2 million pieces annually. This shows how custom silver electrical contacts from drawings improve performance and reduce cost. For more cases, see Silver Contact Applications Guide.
