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).

Precautions
★Please refer to "General Information" for correct use.
Cautions
Correct Use
●Degree of Protection
●Mounting
• Do not use this product underwater.
• Turn OFF the power supply before mounting or removing the
Switch, wiring, or performing maintenance or inspection.
Failure to do so may result in electric shock or burning.
• For M3-screw mounting models, use M3 mounting screws with
plane washers or spring washers to securely mount the
Switch.
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.
JIS C0920:

Tighten the screws to a torque of 0.27 to 0.29 N·m {27.5 to
29.5 gf}. Exceeding the specified torque may result in
deterioration of the sealing or damage.
Degrees of protection provided by enclosures of electrical
apparatus (IP Code)
IEC 60529:
• For models with posts, secure the posts by thermal caulking or
by pressing into an attached device. When pressed into an
attached device, provide guides on the opposite ends of the
posts to ensure that they do not fall out or rattle.
Thermal caulking conditions varies according to the equipment,
jig and base used for switch mounting. Consult your OMRON
sales representative for details.
Degrees of protection provided by enclosures (IP Code)
Degree of protection: IP67
(check water intrusion after immersion
for 30 min. submerged 1m underwater)
• Do not operate the Switch when it is exposed to water spray,
or when water drops adhere to the Switch surface, or during
sudden temperature changes, otherwise water may intrude
into the interior of the Switch due to a suction effect.
• Prevent the Switch from coming into contact with oil and
chemicals.
●Operating Body
• Use an operating body with low frictional resistance and of a
shape that will not interfere with the sealing rubber, otherwise
the plunger may be damaged or the sealing may deteriorate.
Otherwise, damage to or deterioration of Switch materials may
result.
●Handling
• Do not use the Switch in areas where it is exposed to silicon
adhesives, oil, or grease. Otherwise faulty contact may result
due to the generation of silicon oxide.
• Do not handle the Switch in a way that may cause damage to
the sealing rubber.
• When handling the Switch, ensure that pressure is not applied
to the posts in the directions shown in the following diagram.
Also, ensure that uneven pressure or pressure in a direction
other than the operating direction is not applied to the Actuator
as shown in the following diagram. Otherwise, the post,
Actuator, or Switch may be damaged, or the service life may
be reduced.
●Soldering
When soldering the lead wire to the terminal, first insert the
lead wire conductor through the terminal hole and then
conduct soldering.
Make sure that the temperature of the soldering iron tip does
not exceed 300°C, and complete the soldering within 3
seconds. Do not apply any external force for 1 minute after
soldering.
Soldering at an excessively high temperature or soldering for
more than 3 seconds may deteriorate the characteristics of the
Switch.
In case of automatic soldering, please do not apply the heat
beyond 260°C within 5 seconds. Pay careful attention so that
flux or solder liquid does not flow over the edge of the PCB
panel.
●Wiring Molded Lead Wire Models
• When wiring molded lead wire models, ensure that there is no
weight applied on the wire or that there are no sharp bends
near the parts where the wire is drawn out.
Otherwise, damage to the Switch or deterioration in the
sealing may result.
●Side-actuated (Cam/Dog) Operation
• When using a cam or dog to operate the Switch, factors such
as the operating speed, operating frequency, push-button
indentation, and material and shape of the cam or dog will
affect the durability of the Switch. Confirm performance
specifications under actual operating conditions before using
the Switch in applications.
●Using Micro Loads
• Even when using micro load models within the operating
range shown below, if inrush/surge current occurs, it may
increase the contact wear and so decrease durability.
Therefore, insert a contact protection circuit where necessary.
