Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
Precautions for Safe Use
•
Do not disassemble or modify the Switch under any
circumstances. Doing so may cause malfunction.
•
Do not drop or subject the Switch to extreme shock or force.
This may prevent the Switch from functioning to its full capability.
•
The durability of the Switch varies considerably depending on the
switching conditions. Always test the switch under actual working
conditions before application and use the Switch only for the
number of switching operations allowed.
•
Do not allow the load current to exceed the rated value. This may
damage or burn out the Switch.
•
Refer to the Circuit Diagram and make sure to wire correctly. Only
the terminal (1) is printed and the right end of the terminal is read
as (10).

Operating Environment
1. This Switch is intended for indoor use only. Do not use the
Switch outdoors.
2. Do not set the Switch in locations where powders, mud, or any
other substances may be piled, or subject to any splashes of oil
or water. Always test the switch under actual working conditions
before application.
•
Mounting panels
1. Set mounting panel thickness to be 0.8 to 3.2 mm.
2. The panel dimension is set as below;
- The value in ( ) indicated below is the minimum value
suggested for easy detaching of the Switch.
- Minimum panel pitch is 30/32 mm. Consider the flexibility and
allowance of detaching and wiring, set the pitch to the
appropriate value.

•
Do not use the Switch in locations where explosive or flammable
gases or liquid may be present or scattered. The electric ark or the
heat caused by switching contacts may trigger off a fire or
explosion.
•
Do not use the Switch in locations where toxic gases, such as H

, and Cl

, may be present, or in locations subject
to high temperature or humidity. Doing so may damage the Switch
due to contact failure or corrosion.
•
Do not let the Switch submerged in oil or water, or use in locations
continuously subject to splashes of oil/water. Doing so may result
in oil or water entering the Switch.
•
Do not use the Switch in the following locations;
- subject to severe temperature changes.
- subject to high humidity or condensation.
- subject to severe vibration or shock.
- where direct rays of the sun strike.
- where sea breeze may be present.
•
When the Switch is exposed to the environment that are not
required, or stored in locations where condensation presents, or
damaged by fall out, or stored for more than an year, please test it
under the usage conditions before application.
•
Mounting and removing the Switch
1. Insert the Operation Unit to the panel from the front. Install the
lock ring and mounting nut from the terminal side and tighten the
nut. Attach the Switch to the Operation Unit.
2. Align the lock ring with the groove in the casing, and insert it so
that its edge is drawn to the panel side.
3. Tighten the nut to the torque of 0.98 to 1.96
.
4. Snap on the Switch to the Operation Unit, aligning the arrow
marks inscribed on both the Operation Unit and the Switch.
Push the Switch into the Operation Unit until it clicks into place.
5. The push marks on both sides are only for detaching. Do not
push them when you insert the Switch Unit to the Operation
Unit. Otherwise, the Operation Unit is hooked wrongly.
6. To remove the Switch, push to move the levers on both sides in
the direction indicated by PUSH mark. Applying too much
holding force may damage the Switch.
•
Wiring
1. Do not wire the Switch while power is being supplied. Doing so
may result in electric shock.
2. Make sure to insert the connector to the end. This may prevent
the Switch from functioning to its full capability.
3. Do not subject the Switch to an excessive force when wiring. Fix
the cables first to avoid the connector and cables from being
pulled with. Otherwise, the connector may be disassembled or
damaged, resulting in the contact damages.
MIN30
(Reference MIN45)
- Leave some spaces for a finger between panels, so as to pinch
the levers.
- Place the panels in the same direction. Do not set the
connectors face to face for easy removal.
Wrong setup :
Connectors are too closely placed.
Right setup :
Same direction
Levers are too close and
cannot be pushed.
Some rooms for fingers to push.

Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Prod-
uct in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
2.
3.
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
