Custom Electrical Contacts
Stop component failure before it starts. Whether you need solid rivets, welded buttons, or clad strips, our metallurgists help you select the ideal plating and alloy combination to maximize component lifespan and performance.
Why Choose Custom Electrical Contacts?
Your device is only as reliable as its breaking point. Electrical contacts are the critical intersection where mechanical motion meets electrical load. While standard catalog parts may seem cost-effective initially, they often force you to design around their limitations. Custom manufacturing reverses this dynamic—engineering the contact to meet your specific current density, cycle life, and environmental requirements, ensuring the component serves the application, not the other way around.
Avoid Downtime with Precision Fit
Standard contacts often rely on broad commercial tolerances. In high-cycle applications, even microscopic misalignments can lead to mechanical bounce, friction, and premature wear.
We stamp and form contacts to your exact geometric specifications. This ensures perfect mating alignment with your switchgear or relay assembly, reducing mechanical stress and eliminating the mechanical play that leads to system failure and costly maintenance downtime
Enhance Electrical Performance & Safety
Off-the-shelf components limit your material choices to generic copper or brass alloys, which may not handle specific load characteristics effectively. This leads to dangerous overheating, welding (sticking), or excessive arcing.
Customization allows us to engineer the metallurgy. whether you need Silver-Cadmium oxides to prevent welding in high-current surges or gold plating for low-voltage signal integrity. We optimize the mass and surface area to maximize heat dissipation and minimize contact resistance.
Comply with Industry Regulations Easily
Sourcing standard parts from broad distributors often means sacrificing traceability. For industries like automotive, aerospace, or medical, this is a non-starter.
By controlling the manufacturing process from raw strip to finished part, we ensure full compliance with RoHS, REACH, and specific UL standards. You receive full material certification and traceability, simplifying your audit process and guaranteeing the safety of the final product.

- Contact Materials: Fine Silver, Silver-Nickel, Silver-Tin Oxide, and Silver-Cadmium Oxide for high-load switching.
Precision Manufacturing Techniques
We deploy specific manufacturing processes based on your production volume and part complexity:
- Precision Metal Stamping: Utilizing high-speed progressive dies for high-volume production (10k+ units) with consistent tolerances as tight as ±0.01mm.
- Photo Chemical Etching: Ideal for prototypes and intricate flat parts. This burr-free, stress-free process allows for design changes without expensive tooling costs.
- CNC Machining & Wire EDM: For low-volume, thick-gauge, or geometrically complex contacts that cannot be stamped.
- Contact Welding & Riveting:Â Automated in-die welding and staking of contact buttons onto carrier strips for complete assemblies.
Value Added Services Including Plating, Forming and Assembly
A stamped part is rarely the finished product. We deliver ready-to-install components to streamline your supply chain.
- Surface Plating: Rack and barrel plating options including Gold (for signal integrity), Silver (for conductivity), Nickel, and Tin. We also offer **selective plating** to reduce precious metal costs.
- Secondary Operations: Precise bending, forming, and heat treating to lock in spring properties.
- Assembly & Testing:Â Insert molding, tape-and-reel packaging for automated assembly lines, and 100% electrical continuity testing upon request.
Engineering Support & Collaborative Solutions
Successful manufacturing starts before the metal hits the die. We don’t just execute drawings. We analyze them. Our engineering team partners with you to identify potential failure points, reduce material waste, and ensure your electrical contacts are optimized for both performance and mass producibility.
From Prototype to Production
Launching a new product involves risk. We help you manage it by offering a flexible path to volume.
- DFM Reviews: Before tooling begins, we provide Design for Manufacturability (DFM) feedback to suggest minor geometry tweaks that can significantly extend tool life or reduce scrap.
- Rapid Prototyping: We utilize wire EDM or chemical etching to produce functional samples in days, allowing you to validate electrical performance and fit before investing in expensive hard tooling.
- Seamless Scaling:Â Once the design is locked, we transition smoothly from prototype methods to high-speed progressive die stamping for volume cost-efficiency.
Reverse Engineering Legacy Parts
Have a critical component from a supplier that no longer exists? Or a part with lost technical drawings?
- Replication: Send us a physical sample, even if it is worn or damaged. We use high-precision optical measurement systems (CMM) to digitize the part and create new CAD files (STEP/IGES).
- Optimization: We don’t just copy. We often improve. We can recommend modern alloy alternatives that offer better conductivity or durability than the obsolete original materials.
Responsive Engineering Support
In the fast-paced electronics industry, waiting weeks for a quote is unacceptable. We prioritize speed and technical clarity.
- Fast Quoting: We aim to turn around standard RFQs within 24 to 48 hours.
- Direct Access: You won’t get stuck in a phone tree. You will speak directly with project managers and metallurgists who understand conductivity, spring force, and plating specifications instead of just salespeople.
Cut Costs, Not Conductivity
Stop paying for precious metals where you don’t need them. Through Zone Plating (Selective Plating) and smart alloy optimization, we can reduce your material costs by up to 40% while maintaining peak electrical performance.
