6. Special Specification
7. Special Industry Specification
1234 --567
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
