Product Description

WEIPENG® is a leading 16A/21A Iron Pin/Copper Pin High Current Micro Switch manufacturers, suppliers and exporter.

Micro Switch Introduction

The HK-14 switch, developed and produced independently by Yueqing Tongda Cable Factory under the WEIPENG brand, is a large micro switch positioned for the mid-to-high-end market. Thanks to its precise structural design, strict quality control, and versatile adaptability, it plays a key role in various on-off control scenarios. Unlike conventional switch products, it has developed a unique competitive advantage in stability and adaptability, making it a preferred product in the industry that combines practicality and professionalism.

Forced over-travel pressing, misaligned installation with continuous side force on the lever, and long-time high-temperature operation will accelerate aging and cause premature failure far below the rated mechanical life. Reserve reasonable actuation clearance during installation to ensure vertical force without skew. For high-temperature environments, adopt high-temperature resistant microswitches to avoid aging and early damage.
