Spring Loaded Electrical Contacts
Products Description
A Spring Loaded Electrical Contact is a precision connecting element composed of a spring mechanism, conductive contacts, a substrate structure, and a surface coating. Through the continuous pressure of the internal microspring, the contact maintains stable contact with the conductor surface even in dynamic environments, forming a reliable electrical path.
Its core value lies in:
maintaining stable contact under vibration, displacement, wear, and thermal expansion;
suitable for moving structures, small displacement compensation, high-frequency insertion and removal, and environments requiring high reliability;
particularly outstanding in space-constrained, structurally complex, and high-power-density equipment.
Key Product Features
Automatic Pressure Compensation for Stable Contact Force Over Time
The spring mechanism continuously provides appropriate pressure, preventing loosening due to material deformation, environmental changes, or mechanical vibration. This ensures the conductor surface remains in the effective electrical contacts area at all times.
01
Superior Conductive Contact Material Performance
Utilising materials such as silver alloy, silver-nickel, silver-tin oxide, silver graphite, and high-conductivity copper alloy, low switch contact resistance and excellent resistance to electrical abrasion are achieved.
02
Excellent Vibration and Shock Resistance
Even in environments with mechanical vibration and frequent displacement, the spring structure provides immediate compensation, preventing momentary disconnection or instability at the Contactor Contacts.
03
High Cycle Life for Frequent Insertion and Removal Applications
The internal spring automatically adapts to micro-displacements, resulting in more uniform structural stress and extending the overall Electrical Silver Contacts.
04
Multiple Design Forms for Customisation Based on Equipment Structure
Including pin-type, column-type, sheet-type, composite bending, welded, and crimp-type structures, meeting the needs of various terminals, bases, busbars, and precision electrical control systems.

Design Advantages and Details
Micro-dimpled Array on Contact Surface
Electron microscopy reveals a unique micro-dimpled distribution on the contact surface: uniform 0.4μm dimples spaced 1.2μm apart. These dimples are not random but precisely designed through Spring Electrical Contacts dynamics simulation optimisation, ensuring stable point contact under pressure changes and avoiding large-area resistance fluctuations.
Integrated Spring-Contact Structure
The Metal Cold Forming and spring are integrated, avoiding the interface problems of traditional separate structures. Micro-guide grooves are designed at the spring end for more uniform pressure transmission and to prevent stress concentration. This design extends contact life by 40% while ensuring optimal contact performance.
Dynamic Arc Suppression Gradient Zone
A dynamic arc suppression gradient zone is designed at the Silver Contacts In Breakers separation end. This gradient zone is not static but dynamically adjusted according to the separation speed, making the separation process smoother and reducing the probability of arc formation by 90%. High-speed photography shows no spark generation during the separation process.
