Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
WARNING
Do not apply a voltage between the incandescent
lamp and the terminal that is greater than the rated
voltage. If the incandescent lamp is broken, the
Operation Units may pop out.
Always turn OFF the power and wait for 10 minutes
before replacing the incandescent lamp. If the lamp is replaced
immediately after the power is turned OFF, the remaining heat
may cause burns.
Precautions for Correct Use
Mounting
• Do not perform wiring with power supplied to the Switch. Do not
touch the terminals or other charged parts of the Switch while
power is being supplied. Doing so may result in electric shock.
• 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 more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
ring.
The tightening torque is 0.98 to 1.96 N·m.
• Recommended panel thickness: 1 to 5 mm.
• When mounting the caps after changing the LED or the caps,
tighten the caps at a tightening torque of 0.49 tp 0.78 N·m.
LED
• The LED current-limiting resistor is built-in, so internal resistance is
not required.
• If commercially available LEDs are used, select the ones that meet
the following conditions:
Base: BA9S/13
Overall length: 26 mm max.
Power consumption: 2.6 W max.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
• 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.
(Circuit example)
In case of using 24 VAC/VDC, Direct lighting
X1
LED
lamp
R:10kΩ (1W)
Bleeder resistor
X2
Wiring
• Terminal screws must be Phillips or slotted M3.5 screws with a
square washer.
• The tightening torque is 1.08 to 1.27 N·m.
• Solid wires, stranded wires, and crimp terminals can be connected
to the Switch.
Applicable Wire Size
Others
• If the panel is to be finished with coating, etc., make sure that the
panel meets the specified dimensions after the coating.
• Do not subject the Switch to extreme shock or vibration. Doing so
will cause malfunctions and damage to the Switch.
Using the Microload
8 mm max.

8 mm max.
16.0 mm max.
Crimp Terminals with Insulating Sheath
8 mm max.
20.2 mm max.
8 mm max.
20.2 mm max.
• After wiring the Switch, maintain an appropriate clearance and
creepage distance.
• Insert a contact protection circuit, if necessary, to prevent the
reduction of life expectancy due to extreme wear on the contacts
caused by loads where inrush current occurs when the contact is
opened and closed.
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 10−6/operations indicates that the
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60%.

Operating Environment
• The IP65 model is designed with a degree of protection so that it
will not sustain damage if it is subjected to water from any direction
to the front of the panel.
• This switch is intended for indoor use only.
Using the Switch outdoors will result in failure.

Using a Lock Ring
• For 25-dia. holes, always use 25-dia. Rings. (Since the cutout

Rings are used.)
• If outer surface treatment such as coating is performed for the
panel, the panel dimensions after outer surface treatment must

Note: 1. The above dimensions are the minimum dimensions for when the wires
described under Applicable Wire Size on page 23 are used. If a
different wires are used, the wiring dimensions may be different so
determine an appropriate pitch before setup.
2. With pushbuttons of external dimensions greater than 30 mm, set the
pitch according to the dimensions. (When using matrix installation for
the A22-M@, mount with a pitch of 40 mm instead of 30 mm in the
diagram above.)
Mounting the Operation Unit on the Panel
• Insert the Operation Unit (Pushbutton, etc.) from the front surface of the
panel, insert the Lock Ring and the mounting nut from the terminal side,
then tighten the nut. Before tightening, check that the rubber washer is
present between the Pushbutton Unit and the panel.
• When using a Legend Plate Frame, put one rubber washer each
between the Legend Plate Frame and the panel and between the
Operation Unit and the Legend Plate Frame. (One rubber washer
will be provided when one Legend Plate Frame is ordered.)
• Align the Lock Ring with the groove in the casing, then insert the
Lock Ring so that its edge is located on the panel side.
