Four rectangular three-pin microswitches with red dot actuators

YINGHUA

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

SKU CH-W5RF-5R1T6 MPN DMP1101

Four three-pin microswitches rated for 50 million clicks with a 20 gf actuation force

  • Rated for 50 million clicks for extended durability
  • 20 gf actuation force gives a crisp tactile response
  • Red-dot variant designed for improved switch accuracy
  • Three-pin straight-leg layout fits compatible rectangular-foot mice
  • Pack of four switches supports multiple repairs or upgrades

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.
