YINGHUA DMP1101 3-pin 50M click microswitch 4-pack gadget

Three-Pin Microswitch Kit for Mouse Repair

This four-pack supplies YINGHUA DMP1101 switches rated for 50 million clicks each. They suit owners of compatible mice who need to replace worn left or right buttons. The parts arrive new and ready to solder into existing three-pin footprints. Buyers whose mice use a different pin layout or surface-mount design cannot use these switches.

50 Million Click Rating and 0.68 N Actuation Force

The headline spec is the 50 million click lifecycle combined with a 0.68 N (20 gf) actuation force. That pairing defines the tactile crispness and the expected service interval before another swap is needed. Verify that your mouse’s original switch shares the same rectangular three-pin straight-leg geometry before ordering.

Consistent Feel Over Extended Sessions

Manufacturer data describes a medium-short stroke with quick rebound and less lag than comparable switches. The red-dot variant aims to keep that crisp sensation stable during long clicking runs rather than softening after a brief warm-up period. Actual endurance will vary with soldering quality and individual usage patterns.
