Safety Precautions
Refer to Safety Precautions for All Pushbutton Switches/Indicators.
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
operating part 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
• Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
• Do not tighten the mounting nut more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
nut.
The tightening torque is 0.29 to 0.49 N·m.
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 A16 allows both a standard load (125 V at 5A, 250 V at 3 A)
and a microload. If a standard load is applied, however, the
microload area cannot be used. If the microload area is used with a
standard load, the contact surface will become rough, and the
opening and closing of the contact for a microload may become
unreliable.
• 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 × 10-6/operations indicates that the
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60%.
Voltage (V)
WARNING
Wiring
• Solder terminals and quick-connect terminals (#110) are commonly
used for terminals.
• Be sure to use electrical wires that are a size appropriate for the
applied voltage and carry current (conductor size is 0.5 to 0.75
mm2). Perform soldering according to the conditions provided
below. If the soldering is not properly performed, the lead wires will
become detached, resulting in short-circuits.
1. Hand soldering: 350°C, within 3 s
2. Dip soldering: 350°C, within 3 s
Wait for one minute after soldering before exerting any external
force on the solder.
• Use non-corrosive resin fluid as the flux.
• Make sure that the electric cord is wired so that it does not touch
the Unit. If the electric cord touches the Unit, then electric wires with
a heat resistance of 100°C min. must be used.
• After wiring the Switch, maintain an appropriate clearance and
creepage distance.

Operating Environment
• This Switch is intended for indoor use only. Using the Switch
outdoors will cause the Switch to fail. If IP40 models are used in
locations subject to dust, metallic particles, or oil, be careful that
none of these penetrates the Switch.
• The IP66 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.
• Do not use the Switch submersed in oil or water, or in locations
continuously subject to splashes of oil or water. Doing so may result
in oil of water entering the Switch.

Others
• The oil-resistant IP66 uses NBR rubber and is resistant to general
cutting oil and cooling oil. Some particular oils cannot be used with
the oil-resistant IP66, however, so contact your OMRON
representative for details.
• The durability of the Switch depends in the switching conditions.
Always test the Switch under actual application conditions to
confirm applicability and use the Switch only for the number of
switching operations that will not affect performance.
Continuing to use the Switch with degraded performance will
eventually result insulation faults between circuits, burning of the
Switch, or other failures.
• 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 operating parts, and malfunction.
When handling the Switches, do not throw or drop them.
24
A16
• Rubber is used inside IP66 models. Do not allow the rubber to
become scratched or foreign matter to become attached to the
rubber.
Scratches and foreign matter will degrade the waterproofing, and
the Switch may fail operate correctly.
Do not allow the Switch
to drop and hit the
ground.
Precautions
1. The mounting panel thickness must be 0.5 to 3.2 mm.
2. The mounting ring must be tightened to a torque 0.29 to 0.49 N·m.
3. The procedure for making the mounting hole for the screw-less
clamp connector is described on page 21. A mounting dimension
of at least 33 mm is required, however, because the Switch is
removed with the screw-less clamp connector mounted to the
panel. If Switches are mounted side-by-side separated by less
than the specified distance, it may not be possible to remove the
Switch.
4. Be sure to mount the Case to the Switch with the correct
orientation. Mount with the dimple on the Case facing in the same
direction as the side of the Switch with the direction arrow or the
word TOP.

5. Bend the end of the wire if braided wire is used with the screwless clamp connector.
6. When wiring, insert the wire until it comes into contact with
something. After wiring is completed, pull on the wires to confirm
that they are connected securely.
7. After wiring, ensure that continuous pressure is not applied to the
terminals.
8. Refer to internal connection diagrams and confirm the terminal
numbers before wiring.
1. Strip the wires for 10 mm (allowable range: 10± 1 mm).
2. If braided wire is used, twist the wire to straighten it out.
3. Insert the wire into the insertion hole while pressing the release
button at the side of the hole. (Using a precision screwdriver is
recommended.)
4. Let go of the release button to lock the wire into place.
5. After locking, pull on the wire gently to confirm that it is securely
locked.
Removing Wires
1. Remove wires by pulling them while pressing the release button.
Note: When reusing wires that have already been locked one, cut off the end of
the wire and strip the wire again before using.
