  • Blue dot variant rated beyond standard 50M cycles
  • Three-pin straight-leg design fits rectangular micro-switch sockets
  • Two switches included for left and right button repair

What this pack contains

This pack supplies two YINGHUA D2FC-F-K micro switches rated for 50 million clicks and an actuation force of .74N. They use a rectangular three-pin straight-leg layout and a blue-dot actuator. The switches are intended for mouse repair or custom builds that accept this footprint.

Sustained-click behaviour

The 50 million cycle rating is a nominal lifetime figure, not a short-burst specification. Under continuous clicking the mechanism maintains its crisp feel and consistent rebound without the degradation seen in lower-rated alternatives. The conservative rating means the switch stays within specification even after extended daily use.

Thermals noise and power

Micro switches of this type draw negligible current and produce no measurable heat during normal operation. The only audible output is the mechanical click of the blue-dot actuator, which remains consistent over the rated life. No active cooling or special power considerations are required.

Questions about this item

Do these 50 million-click switches run hot or draw extra power during all-day use?

They are passive mechanical components with no power draw and no heat output.

What must I already own to install these .74 N force switches?

You need a mouse that uses rectangular three-pin straight-foot microswitches and basic soldering tools.

Will these blue-dot D2FC-F-K switches fit the same footprint as older D2FC-F models I have?

Yes, they share the same three-pin straight-foot layout, so they drop into the same PCB footprint.
