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

Locking should be applied toward the Engraving Plate.
Note: The above dimensions are the smallest-possible mounting
dimensions. However, these dimensions do not apply to
large Pushbutton Switches. For large Pushbutton
Switches, determine the distance between holes, taking
the Operational Unit and Legend Plate Frame into
account.
JMOUNTING THE OPERATIONAL UNIT
ON THE PANEL
Insert the Operational Unit from the front surface of the panel,
insert the Lock Fitting and the mounting nut from the terminal
side, then tighten the nut. Before tightening, check that the rubber
washer is present between the Operational 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
Operational Unit and the Legend Plate Frame. (One rubber
washer will be provided when one Legend Plate Frame is
ordered.)
Align the Lock Fitting with the groove in the casing, then insert
the Lock Fitting 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{10to
20 kgf cm}.
When using a Lock Ring, replace with the supplied Lock Fitting,
insert the projecting part into the lock slot, and then tighten the
mounting nut.

JENGRAVING
Engrave the characters on the surface on the Cap. Make sure
that the characters are aligned parallel to the imaginary line
connecting the two protruding portions to the left and right of the
Cap.
The characters must not be engraved deeper than 0.5 mm. Apply
an alcohol-based paint coating, such as melamine, alkyd, or
acrylic resin paint coating, to the engraved characters.
Protruding portions on Cap
JAFFIXING CHARACTER FILM
Hold the Cap, remove the cardboard on the Film, and attach the Film
to the Cap. Make sure that the protruding portions of the Cap en-
gage the cutout portions of the Film and that the characters are
aligned parallel to the imaginary line connecting the two protruding
portions to the left and right of the Cap.

direction of the control panel if the Switch is a knob or key
selector model.

To easily remove the Snap-in Legend Plate from the Legend
Plate Frame mounted to the panel, insert a Tool with a thin tip
into the space between the Snap-in Legend Plate and the
Legend Plate Frame.
The Snap-in Legend Plate is easily removed by pressing the
Snap-in Legend Plate from the back of the Legend Plate Frame.
The Legend Plate Frame is made of acrylic resin, which is easily
damaged by shock. Be sure to handle the Legend Plate Frame
with care.
JENGRAVING METHOD
Material: Acrylic
Engrave the characters directly on the matted side of the Snap-in
Legend Plate.
The characters must be engraved no deeper than 0.5 mm.
Apply alcohol-based paint coating to the engraved characters.
If the Snap-in Legend Plate is transparent, engrave the
mirror-written characters on the back of the Snap-in Legend Plate
and apply paint coating to the characters. Then apply paint
coating of a different color to the remaining part of the Snap-in
Legend Plate.
JMOUNTING THREE-THROW SPACER
Press and secure the two protruding portions of the Three-throw
Spacer to the two indented portions of the inner side of the
control panel.
Precautions
WARNING
Do not apply a voltage between the incandescent lamp and
the terminal that is greater than the rated voltage. If the incan-
descent lamp is broken, the Operational 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.
JCORRECT USE
Mounting
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 {10 to 20 kgf cm}.
The panel thickness is 1 to 5 mm.
Wiring
After wiring the Switch, maintain an appropriate clearance and
creepage distance.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
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{11to13kgfcm}.
Single wires, stranded wires, and crimp terminals can be
connected to the Switch.
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.

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% (λ60) (conforming to JIS C5003).
The equation, λ60 = 0.5 x 10-- 4 /time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.

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/13j
Overall length: 26 mm max.
Power consumption: 2.6 W max.
Others
The oil-resistant IP65 uses NBR rubber and is resistant to
general cutting oil and cooling oil. Some particular oils cannot be
used with the oil-resistant IP65, however, so contact your
OMRON representative for details.
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.
Do not let sharp objects come into contact with the Switches that are
made of resin. Doing so will damage the Switches, causing
scratches on the outside of the Operational Units, and malfunction.
When handling the Switches, do not throw or drop them.
Do not allow the Switch
to drop and hit the
ground.
Do not place or drop
heavy objects on the
Switch.
Do not operate the Switch
with hard or sharp objects.
