Yueqing Tongda Micro Switch Factory: 35 Years of Dedication, Forging a Benchmark in Micro Switch Manufacturing

Yueqing, China, [December 10, 2025] — As the core production base of Yueqing Tongda Wired Electric Factory dedicated to the micro switch field, the Micro Switch Factory has developed into a leading professional micro switch manufacturing benchmark in China with mature technology, relying on more than 30 years of manufacturing accumulation, a fully automated production system and strict quality control standards. Focusing on the R&D and manufacturing of micro, precision and high-reliability switches, the factory has an annual production capacity exceeding 30 million units, with products covering home appliances, industrial control, medical care, automotive electronics and other fields, providing customized micro switch solutions for more than 500 enterprises worldwide.

Technological R&D is the core competitiveness of the factory. Relying on the enterprise's provincial-level technology center, the factory has established a professional R&D team of 20 people, accumulating 68 patents related to micro switches. Among them, 12 patented technologies such as "high-precision quick-action trigger structure" and "micro sealed protection technology" are applied to core products. The R&D team can quickly customize personalized parameters such as trigger stroke, operating force and protection level according to customer needs, adapting to diverse scenarios from consumer electronics to industrial control. The delivery cycle of customized products is as short as 7 working days.

The product matrix covers a full range of micro switches, including four categories and more than 200 specifications such as SMD, through-hole, waterproof and illuminated types. The core parameters are aligned with international standards: the mechanical lifespan generally exceeds 100,000 cycles, with a maximum of 1 million cycles; the electrical lifespan ranges from 10,000 to 100,000 cycles; the operating temperature covers -40℃ to 120℃, and the protection level is optional from IP40 to IP67, meeting the usage needs of different environments. All products have obtained international certifications such as UL, VDE and CQC, comply with RoHS and REACH environmental directives, and are compatible with global market access requirements.

A strict quality control system ensures the quality of delivered products. The factory has established a "three-level inspection" mechanism: raw materials undergo 5 inspections including spectral analysis and aging resistance test before warehousing; the production process is monitored in real time through visual inspection and online on-off testing; finished products must pass 12 rigorous tests such as high-low temperature cycle, salt spray corrosion and durability pressing, with a factory qualification rate of 100%. With stable quality and efficient delivery capabilities, the factory has long-term supplied well-known domestic and foreign enterprises such as Midea, Supor and Joyoung, and the global market share of its micro switch products has ranked among the top three in the industry for 5 consecutive years.

"As a professional Micro Switch Factory, we have always adhered to the original aspiration of 'precision manufacturing and reliable empowerment'," said the factory director. In the future, we will continue to invest in intelligent transformation, add 2 AI visual inspection production lines to further improve production efficiency and customized response speed. At the same time, we will expand emerging fields such as new energy vehicles and smart wearables, and consolidate our leading position as a micro switch manufacturing benchmark through technological innovation and scale advantages.
