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

D2HW Sealed Ultra Subminiature Basic Switch Precautions ★Please refer to "General Information" for correct use. Cautions ●Degree of Protection • Do not use this product underwater. Although molded lead wire models satisfy the test conditions for the standard given below, this test is to check the ingress of water into the switch enclosure after submerging the Switch in water for a given time. Satisfying this test condition does not mean that the Switch can be used underwater.
