As the benchmark model of Yueqing Tongda Wire Electric Factory's micro switch series, the 16A Large Micro Switch Household Appliance Heat Resistant 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
The HK-14 adopts a straight-top handleless basic structure, with a standard 3-pin SPDT design combining normally open and normally closed functions. The overall body is compact, compatible with standard switch mounting holes and slot-type fixation, and can directly replace ordinary micro switches of the same specification without additional modifications. The button press feels crisp with a moderate travel, triggering sensitively without sticking, and is not prone to false triggers or contact issues.
