240V Micro Switch Carries "Heavy Current" with Its "Compact Build" in Industrial Control

In the field of industrial automation, a seemingly insignificant component often determines the reliability of the entire system. Yueqing Tongda Cable Factory recently announced a technological breakthrough in its independently developed series of 240V Micro Switches. This component, small as a fingernail, is redefining industry standards with its exceptional electrical performance.

Designed specifically for industrial environments, this micro switch successfully addresses the technical challenge of carrying high voltage within a small form factor. Utilizing special silver alloy contacts and a double-break structure design, the product achieves a rated capacity of 240V/16A while maintaining a compact profile, fully meeting the requirements for control circuits in 380V electrical systems. "Space in automation equipment control cabinets is extremely valuable," stated the company's Chief Engineer. "Our switch provides an electrical capacity two levels higher than conventional products within the same installation footprint."

The product's core competitiveness lies in its extraordinary electrical lifespan. Through an optimized arc-extinguishing system and the use of arc-resistant materials, the switch achieves a mechanical life of over 10 million operations and an electrical life exceeding 500,000 operations under a 240V resistive load. A Quality Director from a well-known frequency converter manufacturer in Zhejiang confirmed: "During control board testing for frequency converters, this switch endured three consecutive months of operation at a frequency of 60 cycles per minute, with performance degradation still within the standard range."

Safety is another standout feature. The switch body is constructed from housing material with a UL94 V-0 flame-retardant rating, and the terminals feature a dual-locking structure to effectively prevent loosening in vibrating environments. These characteristics make it particularly suitable for harsh working conditions, such as those in construction machinery, power distribution, and industrial washing machines.

As industrial equipment trends toward compactness, traditional relays are gradually being replaced by high-capacity micro switches. Yueqing Tongda has taken the lead in this market segment. Currently, this product series has obtained international certifications including UL, CE, and TUV, and has been successfully integrated into products exported to more than twenty countries and regions, including Europe and Southeast Asia.
