Product Introduction

High Current Spring Probes are precision electrical contact components designed to deliver stable and efficient current transmission in demanding power and test environments. Unlike standard signal probes, this type of probe is engineered to handle significantly higher current loads while maintaining low contact resistance, consistent pressure, and long-term mechanical reliability.

Developed by YFS Technology (SZ) Co., Ltd., these high current probes are optimized through careful structural design, advanced material selection, and controlled surface finishing processes. The result is a reliable contact solution capable of operating under high load, repeated compression cycles, and continuous working conditions without performance degradation.

High current spring probes are widely used in power testing fixtures, battery systems, automation equipment, and industrial modules, where stable electrical contact and repeatable performance are essential. The modular design also allows flexible integration into customized fixtures or assemblies, making them suitable for both standardized and application-specific requirements.
