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.
