The Kinghelm KH-12X12X11H-SMT tactile switch is a key product under the Kinghelm brand, featuring high reliability, long operational life, and excellent tactile feel. It adopts a standard 12×12 mm footprint with an 11 mm height in an SMT (Surface Mount Technology) package, making it ideal for modern automated production lines in electronics manufacturing. Weighing approximately 1.864667 g per unit and supplied in tape-and-reel packaging, it is perfectly suited for high-volume SMT assembly, meeting the industry's demands for efficient, automated production.

In terms of design, the Kinghelm KH-12X12X11H-SMT showcases the company's meticulous attention to detail and commitment to quality. Its button is ergonomically optimized for light actuation and crisp rebound, providing users with a comfortable and precise operating experience. Whether in televisions, rice cookers, microwave ovens, or other home appliances and electronic devices, this tactile switch delivers stable and reliable on/off control, meeting users’ needs for precise operation.

From a performance standpoint, the switch offers excellent electrical characteristics. With low contact resistance and high insulation resistance, it maintains superior conductivity and electrical safety under a DC12V 50 mA rated operating condition. The tight control of contact resistance reduces signal loss and the risk of poor contact, while high insulation resistance ensures reliable operation even in humid, dusty, or complex environments, minimizing the risk of short circuits or leakage.

Additionally, the Kinghelm KH-12X12X11H-SMT excels in mechanical performance. It has undergone rigorous lifecycle testing, supporting over 100,000 actuations without performance degradation, demonstrating outstanding durability and reliability. It offers two force options—160±30 gf or 260±50 gf—allowing customization for different device designs and user preferences. To guarantee structural integrity, Kinghelm conducts comprehensive tests on terminal strength and actuator pull strength to ensure that the switch will not loosen or break under reasonable mechanical stress, securing safe and reliable assembly in the final product.

On the manufacturing side, the Kinghelm KH-12X12X11H-SMT uses high-quality materials, including heat-resistant plastics and robust metal contacts. Its SMT package design ensures secure, reliable soldering while significantly enhancing production automation and reducing manual defect rates. The switch has passed 260±5 ℃ reflow soldering thermal tests, hand-soldering heat resistance tests, and solderability tests, demonstrating excellent high-temperature endurance and soldering reliability with no deformation or electrical degradation. This ensures compatibility with the stringent requirements of high-density electronic assembly.

Importantly, Kinghelm is deeply committed to environmental protection and sustainable development. The KH-12X12X11H-SMT is designed and manufactured with strict controls on hazardous substances, meeting RoHS and other environmental compliance standards. For customers, choosing this switch means not only securing a high-quality, stable electronic component but also supporting greener production practices and reduced environmental impact.

In terms of applications, the KH-12X12X11H-SMT tactile switch is widely used in various electronic devices requiring human–machine interaction, including TV remote controls, microwave control panels, rice cooker keypads, small household appliances, smart home control panels, automotive electronics, and industrial control equipment. Its diverse specifications and excellent compatibility make it easy to integrate into different product designs, helping customers achieve efficient, reliable, and aesthetically pleasing user interfaces.

During use, Kinghelm also reminds customers and engineers of several key points. First, follow the recommended reflow or hand-soldering conditions carefully during assembly to prevent deformation of plastic parts or damage to internal contacts from excessive temperature or duration. Second, avoid applying loads beyond the switch's specifications in daily use or design to prevent mechanical failure or electrical faults. If the equipment may contain corrosive gases internally, thorough evaluation and verification are recommended in advance to ensure long-term, stable operation of the tactile switch.
