Precautions
Operation
When operating an A3A, make sure that the A3A has a pushbutton.
Do not operate the A3A with a screwdriver or tweezers without
mounting a pushbutton to the A3A, otherwise the A3A may malfunc-
tion.
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 mecha-
nism 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,
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 sur-
face of the PCB.
Operating Environment
When using an A3A, make sure that dust, metal powder, or oil will
not penetrate into the interior of the A3A.
LED
The polarity of the LED is indicated on the back of the Switch. Wire
the LED correctly according to the polarity.
An A3A with a built-in LED does not have a limiting resistor. Connect
a limiting resistor.
The resistance can be calculated by using the following expression.
R = (E –VF)/IF ()
E:
Applied voltage (V)
VF: LED forward voltage (V)
IF:
LED forward current (A)
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 IF of –10 mA at 24 V and a Ta of 25°C.
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
.
Thus the recommended resistance is 2.2 k
at 0.5 W (2* x IF2R).
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.

Pushbutton
When exchanging the Pushbutton (except the ones for the mechan-
ical 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.
Engraving of Pushbutton
Depth of engraving:
0.3 mm max. for illuminating pushbutton
Since the Pushbutton is made of polycarbonate, use an alcohol-
based solvent when cleaning the Unit.
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.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
