Micro Switch Introduction

Yueqing Tongda has established a comprehensive quality management system covering the entire process from 'raw materials - production - finished products.' The HK-14 series undergoes 16 core tests from raw material warehousing to finished product shipment, including contact resistance testing, insulation performance testing, voltage resistance testing, high and low temperature cycle testing, durability pressing testing, salt spray testing, vibration testing, and more. For each batch of products, 3% are randomly selected for destructive limit testing to ensure a 100% factory pass rate. The company is equipped with 20 fully automated precision production lines, as well as internationally advanced testing equipment (such as the Zeiss coordinate measuring machine from Germany and the Fluke electrical performance tester from the USA) to ensure product accuracy and performance stability.
