Ordering Information
Ordering Individually .........Selectors and Switches can be ordered separately. Combinations that are not available as sets can be created
using individual Units. Also, store the parts as spares for maintenance and repairs.

Safety Precautions
A165K
Refer to Safety Precautions for All Pushbutton Switches.
WARNING
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.
Wiring
• Solder terminals andquick-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, thenelectric 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
• The IP65 model is designed with a degree of protection so that it
will not sustain damage ifit 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 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 themicroload 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 × 10-4/operations indicates that the
estimated malfunction rate is less than 1/2,000,000 operations with
a reliability level of 60%.
