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 reference value: 1.4 mm).
●
Made of environmentally-friendly materials.
All models are lead-free, including molded lead
wire models.
RoHS Compliant
