Ordering set combinations: Refer to page 3 to 5.
The end digit denotes the color
of the flange: -1
denotes a black flange, and -2
denotes a light gray flange.
Round switches are available
only in light gray, and not in
black.
Use the Switch in combination
with the same shape Lamp
(rectangular, square or round).
Example: For rectangular
Lamp A3PJ-5011, select
Switch A3PJ-7@@0-@. On the
Switch itself, however, only 3
digits are shown, as follows:
A3PJ-7@@.
Momentary operation is self-resetting, and alternate operation
is self-holding (i.e., push-on,
push-off).

• Mis-lighting of the LED
The LED lights with approx. 0.1 mA or less of micro-current. Take
a countermeasure like adding a resistor to prevent mis-lighting in
parallel to the LED.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.

Safety Precautions
Refer to Safety Precautions for all Pushbutton Switches/Indicators.
Caution
Precautions for Correct Use
1. Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
Electric shock or fire may occur.
2. After wiring the Switch, make sure that there is a suitable isolation
distance.
Wiring
• Solder quickly and correctly at 350°C max and for 3 s or less.
Wait for one minute after soldering before exerting any external
force on the solder.
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.
Using Microloads
• Using a standard load switch when a microload circuit is opened or
closed may cause contact failure 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 Nlevel 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 10−6/time indicates that the
estimated malfunction rate is less than 1/2,000,000 with a reliability
level of 60%.
Voltage (V)
Do not apply a voltage higher than the maximum
rated operating voltage between the lamp
terminals, as there is a risk that LED will be
damaged, and the Pushbutton will be ejected.

26 mA 100 mA
0.15 mA

LED (for VDC)
• Check the terminal polarity when wiring.
• The rated voltage is shown on the plate on the back of the lighting
unit, so be sure to use within the voltage shown.
• An LED current-limiting resistor is built in, so there is no need to
mount an external resistor.
Character Plate (Character Film)
• If preparing the character plate separately, use a heat-resistant film
with a thickness of 0.1 to 0.3 mm.

Mounting Pushbutton
• Be sure to mount the Pushbutton with the correct orientation. Align
the groove on the Pushbutton, the projections in the Switch, and the
LED contact piece before pushing the Pushbutton into the Switch.
• When dismounting the Pushbutton, use the Extractor (A3PJ-5080)
for easy dismounting.

Mounting and Replacing LED Lamps
If using a square model with one LED lamp, insert the lamp in the
center hole.
Note: Built-in LEDs cannot be replaced.
LED Rated Voltage Display (LED Models Only)
The LED rated voltage is shown between the built-in resistors on the
back of the lighting unit. Use within a range of ± 5%.

Mounting Switch onto Panel
Mounting Colored Plate
Place the colored plate on the plunger case with the dull side of the
colored plate facing downward.
With A3PJ split-screen models, be sure that the projections on the
upper surface of the colored plate face outward. For the A3PA, make
sure that the flat plate is facing upwards.
• Individual Mounting
and Barrier Mounting
When mounting the Switch,
push it into the panel cutout
from the front of the
mounting panel by holding it
with the logo mark
“OMRON” facing downward.
• Multiple Barrier Mounting (A3PJ)
When mounting a number of Switches in
line on the panel, link the Switches with
spacing barriers in between, attach
mounting barriers at both sides of this block
of Switches and, pushing in on the
mounting barriers at the side, insert the
Switches into the panel cutout together.

Mounting Seal Cover
After mounting the seal cover onto the flange of the Switch, push the
Switch into the panel cutout.
Inscribing the Legend Plate
• Inscribe the legend plate to a depth of 0.5 mm max.
• The legend plate is made from polycarbonate resin. To coat the
legend plate, use an alcohol-based coating such as melamine,
phthalic acid, or acrylic.
Maintenance Lock
1. First, when you insert the transparent lens while pressing the
center, the maintenance lock mechanism will be activated, and the
Switch will not operate. Lamp replacement and other maintenance
can be performed without turning OFF the power supply to devices
and equipment. Use an insertion force of 4 kg.
2. Next, when you remove your finger from the Switch, the lock will be
released.
3. The Switch will start to operate when the lighting unit is pressed the
second time.
