Yueqing Tongda Small Push Button: Miniature Empowerment, Precise Control

Yueqing, China, [December 12, 2025] — As a classic product of Yueqing Tongda Wired Electric Factory deeply rooted in the field of micro-control, the Small Push Button has become a core control component in consumer electronics, industrial control, smart devices and other fields after more than 30 years of market iteration, relying on its core characteristics of "compact size, precise triggering, and stable durability". Focusing on the "small size with great function" concept, this product takes adapting to narrow installation spaces and meeting high-frequency operation needs as its core advantages, and has long provided supporting services for well-known domestic and foreign brands, demonstrating the enterprise's technical accumulation and manufacturing strength in the micro-switch field.

Adhering to the design philosophy of "miniaturization + high reliability", the Small Push Button perfectly fits narrow installation scenarios such as smart wearable devices, small control panels, and portable electronic equipment. Integrating multiple patented technologies of the enterprise, it is equipped with high-elasticity beryllium copper reeds and silver alloy contacts, with a trigger response delay of less than 1ms and an operating force of only 40-120g. The pressing feedback is clear and crisp without jamming or sticking, balancing sensitivity and anti-misoperation protection.

Leading core performance in the industry: The mechanical lifespan exceeds 500,000 cycles, and the electrical lifespan reaches 100,000 cycles. Calculated at a daily operation frequency of 50 times, it can run stably for more than 27 years, far exceeding the industry average; The shell is made of flame-retardant PC material (UL94 V-0 grade) with an IP40 protection rating, effectively preventing dust intrusion. The operating temperature ranges from -20℃ to 85℃, adapting to diverse indoor and outdoor environments; The insulation resistance is ≥100MΩ (DC500V), and the terminal withstand voltage is 1500V AC. It has obtained multiple international certifications such as 3C, UL, and VDE, and complies with the RoHS environmental directive, ensuring safe and reliable use.

Comprehensive coverage of diverse scenarios: In the consumer electronics field, it is suitable for Bluetooth headsets, smart watches, portable speakers and other devices. Its miniature size does not occupy internal space, and after being applied by a well-known wearable device brand, the product failure rate has decreased by 55%; In industrial control scenarios, it is used for small PLC controllers and micro-switches of automation equipment. The precise triggering performance ensures the stable operation of equipment, and after being applied by an electronic factory, the production efficiency has increased by 20%; In the smart home field, it is compatible with smart door locks, curtain controllers, small sensors, etc. Its low power consumption and long lifespan characteristics reduce maintenance costs, winning bulk purchases from many smart home brands.

Relying on Yueqing Tongda's ISO9001 quality management system, each Small Push Button undergoes 6 core inspections including raw material testing, online on-off testing, and durability pressing, with a factory qualification rate of 100%. Currently, the product has an annual production capacity of 20 million units, supporting various customized needs such as single control, dual control, and illuminated types, with a minimum delivery cycle of only 7 working days. The person in charge of the enterprise stated that they will continue to optimize product performance, develop waterproof and low-power consumption derivative models, and position themselves as "experts in miniature precise control" to provide stable and reliable control solutions for more emerging fields.
