Precautions
Refer to the Technical Information for Pushbutton Switches (Cat. No.
A143).
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.
Wiring
Solder Terminal
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 mm
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: 30 W, within 5 s
2. Dip soldering: 240 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.
Screw-Less Clamps
Mounting Procedure
1. Strip a length of 10 mm off the end of the wire (allowable range:
2. Bunch wire strands together and straighten them.
3. Insert the wire into the insertion hole while pressing the release
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
Removing Procedure
Remove wires by pulling them while pressing the release button.
Note: When reusing wires that have already been locked, cut off the
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 replac-
ing the incandescent lamp. If the lamp is replaced immediately af-
ter the power is turned OFF, the remaining heat may cause burns.

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.
Using the Microload
Insert a contact protection circuit, if necessary, to prevent the reduc-
tion 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% ( 60) (conforming to JIS C5003).
The equation,
mated malfunction rate is less than 1/2,000,000 operations with a
reliability level of 60%.
LED
The LED current-limiting resistor is built-in, so external resistance is
not required.
Note: The values in parentheses are for models with blue or red
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 representa-
tive for details.
