• Direct opening mechanism to open the circuit when the contact
welds .
• Safety lock mechanism prevents operating errors.
• Easy mounting and removal of Switch Blocks using a lever.
• Mount three Switch Units in series to improve wiring efficiency
(with non-lighted Switch Units, three Units can be mounted for
multiple contacts).
• Finger protection mechanism on Switch Unit provided as a
standard feature.
• Install using either round, or forked crimp terminals.
• Oil-resistant to IP65 (non-lighted models)/IP65 (lighted models)
• A lock plate is provided as a standard feature to ensure that the
control box and switch are not easily separated.

Installation
Mounting to the Panel
(1) Preparing the Panel (2) Mounting the Operation Unit on the Panel
• The panel dimensions are shown below.
• The panel thickness must be 1 to 5 mm.
• Always use a 25-mm-dia. Lock Ring for a 25-mm-dia. hole.
IP65 degree of protection will be lost if the 25-mm-dia. Lock Ring is not
used because of the larger size of a 25-mm-dia. hole.
• When painting or coating the panel, make sure that the specified panel
dimensions apply to the panel after painting or coating.
• Insert the Operation Unit from the front surface of the panel, insert the Lock Ring and
the mounting Ring from the terminal side, then tighten the Ring. Before tightening,
check that the rubber washer is present between the Operation Unit and the panel.
• 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.
• 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 Ring.
(3) Mounting the Switch on the Operation Unit
• Insert the Operation Unit into the Switch Unit, aligning the arrow mark
inscribed on the Case with the lever on the Switch Blocks, then move the
lever in the direction indicated by the arrow in the following figure.
(4) Removing the Switch
• Move the lever in the direction indicated by the arrow in the following
figure, then pull the Operation Unit or the Switch Blocks.
Since the lever has a hole with an inside diameter of 6.5 mm, the lever can
be moved in the specified direction by inserting a screwdriver into the hole
and then moving the screwdriver.

The Standard-size Legend Plate Frame can
be mounted.
Mount the Frame as shown in the following
diagram. Mount the Switch in the same way
as for an ordinary panel.
Place the tip of a screwdriver on the surface
where the cable port hole is to be created
with the cover attached and strike the
screwdriver to punch a hole.
Attempts to punch a hole on the other side
of the case will damage the Box.
1. Insert the connector into the cable port hole in the Box and secure
with the Mounting Ring inside the box.
2. Pass the tightening cap through the cable, insert the cable into the
connector, and tighten the tightening cap to secure the cable.

Safety Precautions
Be sure to read the precautions for All PushButton Switches in the website at:http://www.ia.omron.com/.
Indication and Meaning for Safe Use
!CAUTION
Mounting
•Always make sure that the power is turned OFF before wiring the
Switch. Also, do not touch the terminals or other current-carrying
ports while power is being supplied. Electric shock may occur.
•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.
Mounting the Lock Plate
1. Confirm that the lever on the Mounting Latch is on the side where
the Operation Unit is secured and then insert the protrusion on the
Lock Plate into the hole in the lever on the Mounting Latch.
2. Press the hole on the Lock Plate onto the protrusion on the
Mounting Latch until it clicks into place.
(1) Installing the Switch Blocks (2) Removing the Switch Blocks Wiring
• Hook the small protrusion on the Mounting Latch
into the groove on the other side of the lever, then
push up the Switch Block in the direction indicated
by the arrow in the figure below.
• Insert a screwdriver between the Mounting Latch
and the Switch Block, then push down the
screwdriver in the direction indicated by the arrow
in the following figure.
• Loosen the terminal screw from the Switch
Unit until it completely comes off the groove,
insert a screwdriver as shown in the following
figure, then push up the washer in the
direction indicated by the arrow to temporarily
secure it.
Now, a round crimp terminal can be
connected. After inserting the terminal, tighten
the screws to complete wiring.

Precautions
for Safe Use
Supplementary comments on what to do
or avoid doing, to use the product safely.
Do not apply a voltage exceeding the rated voltage across
the incandescent lamp terminals.
The lamp may be destroyed and the operation unit may fly
out.
If the Operation Unit is separated from the Socket Unit, the
equipment will not stop, creating a hazardous condition.
Secure the lever on the Socket Unit by using the
A22Z-3380 Lock Plate so that the Operation Unit cannot
be easily separated from the Socket Unit.
(Refer to “Mounting the Lock Plate” at the right.)

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.
•Single wires, stranded wires, and crimp terminals can be
connected to the Switch.
•Applicable Wiring Materials:
Twisted strands: 2 mm2 max.
Solid wire: 1.6 mm dia. max.
•After wiring the Switch, maintain an appropriate clearance and
creepage distance.
Operating Environment
•The IP65 model is designed with a protective structure so that it will
not sustain damage if it is subjected to water from any direction to
the front of the panel.
•The Switch is intended for indoor use only. Using the Switch
outdoor may cause it to fail.
LEDs
•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.
Using the Microload
Contact failure may occur if a Switch designed for a standard load is
used to switch a microload. Use Switches within the application
ranges shown in the following graph. Even within the application
range, 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/time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of 60%.
Others
•If the panel is to be coated, make sure that the panel meets the
specified dimensions after coating.
•Due to the structure of the Switch, severe shock or vibration may
cause malfunctions or damage to the Switch.
Also, most Switches are made from resin and will be damaged if
they come into contact with sharp objects. Particularly scratches
on the Operation Unit may create visual and operational
obtrusions.
Handle the Switches with care, and do not throw or drop them.
