The Micro Push Button Undergoes A Major Upgrade, Setting A New Benchmark For Switch Technology

Yueqing, November 12, 2025 — Yueqing Tongda Wired Electric Factory, founded in 1990 with 35 years of experience in the switch industry, announced today the completion of core technological upgrades for its Micro Push Button series. Leveraging the patented technology of "easily replaceable micro switches", the series has achieved key breakthroughs in triggering precision, assembly-disassembly convenience, and environmental adaptability, successfully entering high-end scenarios such as smart homes, medical instruments, and automotive electronics, and injecting new momentum into the rapidly growing micro trigger switch market.

As a core triggering component of electronic devices, the Micro Push Button features "small size and high precision", and is widely used in key control links such as equipment startup and function switching. This upgrade specifically optimizes industry pain points: adopting a dual-core structure of "gold-plated contacts + reinforced shrapnel", the initial contact resistance is ≤20mΩ, the triggering stroke is precisely controlled at 0.5-1.0mm, and the operating force is adjustable between 3-6N, meeting the dual needs of "light-touch precise triggering" for medical equipment and "anti-misoperation" for industrial equipment; the mechanical lifespan exceeds 1.5 million cycles, and the electrical lifespan reaches 80,000 cycles, far exceeding the industry average, making it suitable for high-frequency operation scenarios.

Targeting different application environments, the series provides diversified solutions: the basic version adopts a flame-retardant ABS shell with an IP40 protection level, suitable for dry scenarios such as office equipment and consumer electronics; the waterproof version upgrades the potting sealing process to achieve IP67 protection, which can resist the erosion of humid and rainy environments, and is suitable for outdoor equipment and automotive electronics; the high-temperature version uses high-temperature resistant PA66 material, with the operating temperature range expanded to -40℃ to 125℃, meeting the harsh working conditions of industrial automation equipment.

A strict quality control system ensures product reliability. Relying on a fully automated assembly line, the key dimensional error is controlled within ±0.01mm, and each finished product must pass 8 tests including high-low temperature cycle, salt spray corrosion, and durability pressing. Currently, the products have obtained international certifications such as UL, VDE, and CQC, comply with the ISO 13485 standard for medical devices and the IATF16949 standard for the automotive industry, and maintain a 100% factory qualification rate.

The market implementation results are remarkable: in the medical field, supporting a brand of portable diagnostic instruments, it realizes precise key operation, reducing the equipment mis-trigger rate by 72%; in the smart home scenario, adapting to the emergency call button of smart door locks, it reduces after-sales maintenance costs by 60% by virtue of its long lifespan advantage; in the automotive electronics field, the customized version is used for the control of new energy vehicle charging guns, and has passed 12 months of actual vehicle testing without faults, winning bulk orders.

"The upgrade of the Micro Push Button is our practice based on patented technology and responding to the diverse needs of the market," said the enterprise's person in charge. In the future, we will keep up with the intelligent trend, develop low-power consumption and intelligent versions with signal feedback, further expand emerging application scenarios such as wearable devices and industrial robots, and continuously consolidate the advantages in the segmented market.
