Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches.
CAUTION
Do not apply a voltage higher than the maximum
rated operating voltage between the lamp terminals,
as there is a risk that the incandescent lamp or LED
lamp will be damaged, and the Pushbutton will be
ejected.
When replacing the incandescent lamp, first turn OFF
the power supply, and then wait 10 minutes before
performing replacement, as the lamp is still hot
immediately after the power is turned OFF, so there
is a risk of burns.
Precautions for Correct Use
Using Microloads
• Using a standard load switch for opening and closing a microload
circuit may cause wear on the contacts. Use the switch within the
operating range. (Refer to the diagram below.) Even when using
microload models within the operating range shown below, if inrush
current occurs when the contact is opened or closed, it may cause
the contact surface to become rough, and so decrease life
expectancy. Therefore, insert a contact protection circuit where
necessary. The minimum applicable load is the N-level reference
value. This value indicates the malfunction reference level for the
reliability level of 60% (λ 60) (conforming to JIS C5003). The
equation, λ 60 = 0.5 x 10−4/times indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.
Voltage (V)
Mounting
• To prevent electric shock or a fire, always make sure that the power
is turned OFF before mounting, removing, or wiring the Switch, or
performing maintenance.
• Do not tighten the mounting ring excessively using pliers or a similar
tool. Excessive tightening may damage the mounting ring.
(Tightening torque: 0.20 to 0.39 N·m)

Operating Environment
• Do not use in locations that are subject to dust, oil, or metal filings
as these may penetrate the interior of the Switch and cause
malfunction.

Wiring
• When wiring, use wires of a size appropriate for the applied voltage
and carry current. Perform soldering correctly under the conditions
given below. Using the Switch with the wires soldered incorrectly
may cause the terminals to become abnormally hot and cause a
fire.
1. Soldering iron tip temperature: 350°C max. within 3 seconds.
2. Dip soldering: At 350°C within 3 seconds.
Wait for one minute after soldering before exerting any external
force on the solder.
• Use a non-corrosive rosin liquid for the flux.
• Perform wiring so that the wire sheaths do not come into contact
with the Switch. If this is unavoidable, use wires that can withstand
temperatures of 100°C min.
• After wiring to the Switch has been completed, ensure an
appropriate insulation distance.

Lighted Pushbutton Switch
• Insert the Lamp (incandescent lamp or LED lamp) into the
Pushbutton so that the lamp guide fits into the wider gap between
the projections on the Pushbutton.

• Insert the Switch from the front of the panel. Mount the mounting
nut from the terminal end of the Switch and tighten it.
• There are projections on the terminal end of the Switch which may,
depending on the orientation, block the nut. In this case, turn the nut
until it is possible to mount it. Tighten the nut to a torque between
0.20 and 0.39 N·m.
• If soldering is used, mount the mounting nut first. Lead wires and
mounds of solder may make it impossible to mount the nut after
soldering.

Note: 1. The mounting direction for Indicators is 180° to that for Lighted
Pushbutton Switches. Be sure to insert the Legend Plate and other
parts with the correct orientation.
2. If the terminals of the Lamp become bent, it may be impossible to fit
them into the lamp terminal holes. Ensure that the terminals are
straight when they are inserted.
3. Take particular care about the mounting direction with the round
models (A3CT).
(3) Removing the Pushbutton/Display
Hold the recessed portions on the cap of the Pushbutton and pull.
• After securing the Switch to the panel using the mounting nut, pass
the lead wires through the holes in the Insulation Cover and then
perform wiring. Hold the Insulation Cover so that the cylindrical hole
is facing the Switch, and insert the lead wires from the end with the
barriers.
• After wiring is completed, mount the Insulation Cover by pushing it
into the Switch.

Mounting the Dust Cover
1. The Dust Cover separates into 2 parts: the cap and the mounting
frame.
2. Insert the Switch into the mounting frame. (Align the lock
projection with the recess on the mounting frame.)
3. Insert the Switch in the state described in step 2 into the panel.
(Align the lock protrusion on the mounting frame with the hole in
the panel.)
4. Mount the mounting nut from the back of the panel and tighten it.
5. Insert the cap into the mounting frame. Ensure that the entire
perimeter of the cap is properly inserted into the mounting frame
by pressing down on the cap from different directions.

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 Product 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 equipment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.
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

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 suitability 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 requirements. 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 practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special 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.
