As the benchmark model of Yueqing Tongda Wire Electric Factory's micro switch series, the 2-Pin 16A Long Lever High-Power Household Appliance High-Temperature Resistant Micro Switch Resistant Micro Switch Resistant Micro Switch features "high sensitivity, ultra-long lifespan, and multi-scenario adaptability" as its core advantages. Integrating the company's 35 years of switch manufacturing expertise, it has become a key control component in household appliances, automotive electronics, industrial automation, and other fields, thanks to its minimal contact gap and rapid action mechanism.
Micro Switch Introduction
Featuring a rugged sealed housing and high-temperature resistant materials, the HK-14 maintains stable electrical characteristics even in environments with vibration, dust, and temperature fluctuations. Its standardized mounting dimensions and versatile terminal design allow easy integration into assembly lines, home appliances, power tools, and industrial control systems, reducing installation complexity and improving production efficiency.
General IP40 microswitches have limited dust and splash resistance. In kitchens, bathrooms and humid outdoor environments, moisture and oil fume easily penetrate inside, causing contact rust, short circuit and malfunction. It is recommended to upgrade to IP41 or higher protected microswitches and strengthen equipment sealing to prevent moisture and oil fume intrusion.
