Bimetal Silver Contacts For Switch
Products Description
Bimetal Silver Contacts for Switches are core current-carrying components within various power switches and relays, achieving integrated conductivity, heat dissipation, and mechanical assembly through a dissimilar metal composite structure. In large-scale new energy systems such as new energy storage, photovoltaic converters, and vehicle powertrains, contacts play a crucial role in connecting and disconnecting load current. When system integrators build a complete power control chain, the arc resistance and contact resistance stability of the contacts directly affect the continuous operating life of the entire system. We offer standardized and customized bimetallic silver contacts to match the harsh operating conditions of new energy power electronics systems, ensuring the long-term coordinated and stable operation of the entire control system.
Product Structure Disassembly
- Surface Layer: The surface layer of the Spring Loaded Electrical Contacts is a silver alloy functional layer that directly withstands arc impact, responsible for conductivity and resistance to arc erosion.
- Bottom Layer: The bottom layer of the Electrical Bimetal Rivet is a copper substrate layer, responsible for mechanical riveting fixation, rapid heat conduction, and reducing overall resistivity.
The two metal layers are tightly bonded through a solid-state composite process, eliminating the risk of delamination or layering. The integrated rivet design allows the finished Electrical Sliding Contacts to directly serve as the core conductive component inside the switch, widely used in various relays and limit switches.
Technical Features
Bimetallic Metallurgical Composite Technology
A metallurgical-grade bond between the silver and copper layers is achieved through cold forging and high-pressure composite processes. The interface is free of pores and oxide inclusions, resulting in a bonding strength far exceeding that of traditional riveting or welding processes.
Material Formulation Customization Capability
Various material formulations, such as AgNi and AgSnO₂, are available based on customer current ratings, breaking cycles, and environmental requirements. The silver content can be adjusted to optimize the performance of the Electrical Bimetal Rivet.
Precision Dimensional Control Technology
Utilizing a multi-station cold heading machine and an online inspection system, the dimensional stability of Normally Open Limit Switch Electrical Contacts is ensured during mass production.
Surface Microstructure Optimization Technology
By optimizing polishing process parameters, the surface roughness and texture direction of the Switch Electrical Contact are controlled, reducing initial contact resistance and suppressing fretting wear.
Comparison with Competitors
Process Level
The entire cold heading process is handled in-house, eliminating the outsourcing of forming processes. This ensures batch consistency of Leaf Spring Electrical Contacts superior to those from external processing manufacturers.
Supply Chain Level
In addition to producing Silver Cadmium Electrical Contacts, it can simultaneously supply all metal components for relays, enabling one-stop procurement and reducing the cost of managing multiple suppliers.
Engineering Adaptation Level
Supports customization of silver layer thickness and alloy formulation for Composite Contact Rivets for Relay based on system operating conditions, rather than simply providing fixed standard parts.
Risk Management
Maintaining a stable raw material inventory and locking in materials in advance mitigates supply risks caused by commodity price fluctuations and raw material delivery delays.
