As the core micro switch developed by Yueqing Tongda for general-purpose precision control scenarios, the HK-20 series is positioned around 'compact design and fast, precise triggering.' With 38 years of experience in micro switch manufacturing, it combines sensitive response, long lifespan, and broad adaptability, making it a key component for circuit control in consumer electronics, industrial control, smart home devices, and more, providing reliable travel detection and functional on/off solutions for equipment.
Micro Switch Introduction
The Smart Door Lock Mouse Switch features a minimalist, ultra-compact design, with overall dimensions of only 18×10×6mm, reducing the size by 15% compared to conventional micro switches. It can be easily embedded in devices with limited space, such as small sensors, portable electronic devices, and precision instruments. Its installation is flexible, supporting three mounting methods: PCB plug-in, soldering, and snap-in. The terminals are standardized in spacing, requiring no modification to the device mounting points, improving assembly efficiency by 40% and reducing manufacturers' production adaptation costs.
The trip control module embedded in smart curtains, electric height-adjustable desks, and robotic vacuum cleaners enables automatic start and stop by accurately detecting the operating position of the device. The micro-size and low-power characteristics of the HK-10 help achieve lightweight and long-lasting designs for devices. A smart home brand reported that after integration, the product's battery life was increased by 10%.
