Vertical-Mount Design with Gull-Wing Terminals

The Kinghelm KH-4.5X4.5X8H-STM tactile switch features a vertical surface-mount design with gull-wing terminals, allowing for secure PCB mounting and compatibility with automated SMT assembly—perfect for large-scale production. Compared to traditional through-hole tactile switches, this vertical structure saves vertical space and helps create a more compact internal layout, particularly beneficial for designs where thickness is a critical constraint.

Refined Appearance and Reliable Feedback

This tactile switch includes a round black button with a finely textured surface, providing crisp, responsive tactile feedback with moderate actuation force—enhancing the user interaction experience. The standard SPST (Single Pole Single Throw) circuit structure ensures clear logic and simple operation, ideal for circuits that require single-action triggers. Despite its compact size, the switch delivers stable mechanical strength and long operational life, making it suitable for high-frequency control interfaces.

Technical Specifications

With overall dimensions of 4.5mm × 4.5mm × 8mm, the switch's precise construction ensures fast, accurate actuation with minimal false triggers. Weighing just 0.511 grams, it adds negligible weight to the host device, making it especially suitable for lightweight electronics. The bracketless design also enables dense switch arrangements on a panel, supporting highly integrated control panel layouts.

Broad Applications Across Industries

In consumer electronics, the KH-4.5X4.5X8H-STM tactile switch is commonly used in audio control panels, remote controls, Bluetooth earbud charging cases, and game controllers, where its compact form factor and satisfying tactile feedback enhance end-user experience. It also sees widespread use in smart home control panels for functions like scene switching, lighting control, and volume adjustment, where reliability over extended periods is key.

In the fields of medical equipment and industrial automation, this switch excels with its precise response and noise resistance, ensuring accurate control even in complex environments. For embedded devices, communication modules, and various instrument panels, the uniform design and flexible layout options support streamlined integration and easier maintenance.
