D2HW Sealed Ultra Subminiature Basic Switch
Smallest sealed snap-action switch in the industry with a very long stroke for reliable ON/OFF action.
  • The case dimensions are 78% of conventional models, contributing to down-sizing of mechanical modules.
  • Extra-long stroke even without levers. (OT: 1.4 mm)
  • Made of environment-friendly materials. All models are lead-free, including molded lead wire models.
