Precautions
● Refer to the “Push-button Switches Common Precautions” for correct use.
Precautions for Correct Use
Lighted Pushbutton Switch
? 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.
● Mounting
? When opening a hole on a panel to
mount an A3A to the panel, make sure
Note: Make sure that the limiting resistor
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.
● Example
Conditions: Red LED with an I F of
–10 mA at 24 V and a Ta of 25°C.
From the red LED characteristic below,
V F will be 2 V when I F is 10 mA.
● Pushbutton
? 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.

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.
● Wiring
? When soldering the terminals of an
A3A, refer to the following.
1. For manual soldering:
Use a soldering iron with the
terminals at a temperature of 350°C
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,
Therefore, R = (24 V – 2 V)/0.01 A =
2,200 Ω .
Thus the recommended resistance is
2.2 k Ω at 0.5 W (2* x I F2 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.

● 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.
● Pressing of Pushbutton
? Apply firm pressure to the Pushbutton
when operating it. In doing so,
however, do not apply a pressure
greater than 11.8 N.
otherwise the joint part of the A3A may
be damaged.

? 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.

correctly according to the polarity.
? An A3A with a built-in LED does not
have a limiting resistor. Connect a
limiting resistor.
