Product Description: TDF-06108 Series LED Illuminated Tactile Switch IP67 Rated

The TDF-06108 Series represents a pinnacle of tactile switch engineering, combining compact surface-mount design with vibrant LED illumination to deliver both functional reliability and aesthetic appeal. Designed for applications where space is at a premium and user feedback is critical, this 6.1mm x 6.1mm package offers a robust solution for consumer electronics, medical devices, automotive controls, and outdoor or industrial equipment.

Superior Environmental Protection
One of the standout features of the TDF-06108 Series is its industry-leading IP67 waterproof and dustproof rating. This certification guarantees that the switch is completely sealed against dust ingress and can withstand immersion in water up to 1 meter for 30 minutes without performance degradation. This rugged protection makes it an ideal choice for applications exposed to moisture, spills, or harsh environmental conditions, such as marine electronics, handheld instruments, kitchen appliances, and outdoor control panels, ensuring long-term reliability and user safety.

Precision Engineering and Optical Feedback
At the heart of this component is a clear rubber actuator that stands 5.0mm off the PCBA, providing a distinct, responsive tactile feel. With a crisp travel distance of 0.25mm, it delivers precise actuation, ensuring users are never in doubt of a successful keypress. The switch is rated for a power supply of DC 12V at 50mA and is available in two distinct operation forces—200gf for a light, sensitive touch, and 270gf for a firmer, more deliberate press. This allows engineers to select the perfect resistance for their specific user interface requirements.

The integrated illumination elevates the user experience significantly. The TDF-06108 Series offers a versatile palette of LED color options, including White, Blue, Green, Red, and Yellow. This feature not only enhances visibility in low-light conditions but also allows for intuitive color-coding of functions, adding a premium layer of interactivity to the end product.

Superior Mounting and Assembly Advantages
Beyond its electrical and tactile performance, the TDF-06108 is engineered for manufacturing excellence. It features an innovative board guide on the underside of the switch. This design serves two critical purposes:

1. Enhanced Stability: During the reflow soldering process, the guide anchors the switch securely to the board, preventing misalignment or “swimming” as solder paste liquefies. This ensures consistent, reliable solder joint formation and a perfectly straight final assembly.
2. Mistake-Proofing: The guide acts as a mechanical polarizing feature. When populated onto the PCB, it prevents incorrect orientation of both the switch terminals and the LED terminals, eliminating the risk of costly assembly errors and reverse polarity issues on the production line.

Direct Drop-In Replacement Compatibility
The TDF-06108 Series has been meticulously designed to match the form, fit, and function of industry-standard models, specifically the Samesky CUI switches: TS24-62-14-BL-200-SMT-TR-67, TS24-62-14-CL-200-SMT-TR-67, and TS24-62-14-CL-250-SMT-TR-67. Sharing identical dimensions, actuation heights, and critical electrical parameters, our switch offers a seamless, drop-in alternative. This compatibility allows customers to diversify their supply chain, secure competitive pricing, and ensure long-term availability without undergoing any costly PCB redesigns or requalification processes. The TDF-06108 is the smart, reliable choice for modern, illuminated user interfaces that demand both visual sophistication and environmental resilience.
