Safety Precautions
A22
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
WARNING
Do not apply a voltage between the LED and the terminal that is greater than
the rated voltage. If the LED 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.
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
Stranded wire: 2 mm2 max. Solid wire: 1.6 dia. max.
Bare Crimp Terminals
8 mm max.
8 mm max.
16.0 mm max.
16.0 mm max.
Crimp Terminals with Insulating Sheath
8 mm max.
8 mm max.
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:10k (1W) Bleeder resistor
X2
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
· 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% ( 60) (conforming
to JIS C5003). The equation, 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%.
20.2 mm max.
20.2 mm max.
· After wiring the Switch, maintain an appropriate clearance and creepage
distance.
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.

· For 25-dia. holes, always use 25-dia. Rings. (Since the cutout dimensions
are large, IP65 cannot be guaranteed unless 25-dia. Rings are used.)
· If outer surface treatment such as coating is performed for the panel, the
panel dimensions after outer surface treatment must meet the specified panel
dimensions.

Note: 1. The above dimensions are the minimum dimensions for when the wires
described under Applicable Wire Size on page 21 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.
22
· Tighten the mounting nut at a torque of 0.98 to 1.96 N·m. · When using a
Lock Ring, replace with the supplied Lock Ring,
insert the projecting part into the lock slot, and then tighten the
mounting nut.
