Note: The above models each have a SPST-NO contact that can switch 6 A at 125 VAC, 2 A at 250 VAC, and 4 A at 30 VDC. When ordering any of the above models,
replace @ of the model number with a code to indicate the pushbutton color of the model (i.e., replace @ with R, Y, G, L, A, B, D, H, and L). The pushbutton of
an A3A does not illuminate if the color of the pushbutton is dark gray, gray, light gray, blue, or black.

Precautions
●Refer to the “Push-button Switches Common Precautions” for correct use.
Precautions for Correct Use
Note: Make sure that the limiting resistor
• Please do not perform wiring or touch
the charged parts of terminals while
power is supplied to the Switch.Doing
so may result in electric shock.
• Make sure to keep a secure insulation
distance after wiring to the Switch.
● Pushbutton
connected to the built-in LED of an A3A
satisfies the characteristics of the built-in
LED. The mean forward current of the
built-in LED must be 8 mA minimum.
• When exchanging the Pushbutton
(except the ones for the mechanical
indicator models) with a new one, pull
out the Pushbutton from the Switch,
holding the Pushbutton in the
longitudinal direction.
Do not remove the Pushbutton of the
mechanical indicator model.
● Example
Conditions: Red LED with an IF of
–10 mA at 24 V and a Ta of 25ꢀC.
From the red LED characteristic below,
VF will be 2 V when IF is 10 mA.
Therefore, R = (24 V – 2 V)/0.01 A =
2,200 Ω.
● Mounting
• When opening a hole on a panel to
mount an A3A to the panel, make sure
that the hole has no burr.
• When mounting a flange to the
switching mechanism of an A3A,
make sure that the flange and the
casing of the switching mechanism
are engaged securely.
A

A
● Engraving of Pushbutton
• Depth of engraving: 0.3 mm max. for
illuminating pushbutton
• Since the Pushbutton is made of
polycarbonate, use an alcohol-based
paint when marking legend.
Thus the recommended resistance is
2
2.2 kΩ at 0.5 W (2* x IF R).
Note: A factor of 2 (marked with an asterisk) is
applied because the permissible wattage of
the resistor must be twice as large as the
required wattage.
● Wiring
● Pressing of Pushbutton
LED Characteristics
• When soldering the terminals of an
A3A, refer to the following.
1. For manual soldering:
• Apply firm pressure to the Pushbutton
when operating it. In doing so,
however, do not apply a pressure
greater than 11.8 N.
(VF – IF Characteristics)
Ta: Ambient Temperature
Use a soldering iron with the
terminals at a temperature of 350ꢀC
maximum within three seconds.
2. Do not impose any external force on
the terminals for one minute after
the terminals are soldered.
• Do not pull the terminals of any A3A
with a force exceeding 5.34 N,
otherwise the joint part of the A3A may
be damaged.

• When soldering the terminals of an
A3A, apply non-corrosive rosin flux to
the terminals.
• After soldering the terminals of an
A3A, do not wash the A3A with any
solvent.
• When mounting an A3A to a PCB and
soldering the terminals of the A3A to
the PCB, make sure that the flux will
not rise above the surface of the PCB.

■Installation
● Mounting and Replacing the Pushbutton
1. Mounting Direction for the
Pushbutton and Switch
2. Removing the Pushbutton (Non-lighted Models Only)
• Insert the catches of the Pushbutton into the
grooves of the Switch and push down on the
Pushbutton until it is fixed securely to the
Switch.
• To remove the Pushbutton, hold both the
Pushbutton and the Switch on the longer
sides and pull the Pushbutton away from the
Switch.
• When replacing the Pushbutton, if the cap is held
on the sides with catches, internal components
(e.g., plate) may come loose. Be sure to hold the
Pushbutton by the sides without catches (i.e., the
longer sides of the Switch) when removing.
• With lighted models, the LED is built into the
Switch and cannot be replaced.
(If the catches on the Pushbutton are bent
outwards, it may result in malfunction.)
