pass the lead wires through the holes in the Insulation Cover
before performing wiring. Hold the Insulation Cover so that the
cylindrical hole is facing the Switch, and insert the lead wires
from the end with the barriers.

Installation
If soldering is used, mount the mounting nut first. Lead wires and
mounds of solder may make it impossible to mount the nut after sol-
dering.

Curved claw
Projection

Pushbutton
Align the curved claw on the outside of the protruding part of the
Pushbutton with the projection on the upper part of the Switch and
insert.
Socket Mounting
After securing the Switch to the panel using the mounting nut, insert
the Socket into the Switch.
Apply a pressure between 9.8 and 24.5 N.
Note: If the terminals of the LED lamp become bent, it may be
impossible to fit them into the LED lamp terminal holes.
Ensure that the terminals are straight when they are
inserted. Be sure to insert the lamp terminals for round
models with the correct orientation. Inserting the terminals
with the reverse orientation will result in damage.
When inserting the Socket, align the positioning groove of the
Socket with the projecting part of the Switch.

Panel Mounting
Using the Mounting Nut
Insert the Switch from the front of the panel. Mount the mounting nut
from the terminal end of the Switch and tighten it.
Tighten the nut to a torque 0.20 to 0.39 N⋅m.

Precautions
Refer to the Common Precautions for Pushbutton Switches on
Calculation Example for Limiting Resistance
page 14.
Conditions: Red LED with an I of 20 mA at 24 V and a Ta of 25°C.
F
From the red LED characteristic given previously, V will be 1.7 V
F
Correct Use
Mounting
when I is 20 mA. Therefore, R = (24 V – 1.7 V)/0.02 A = 1,100 Ω.
F
2
Thus the recommended resistance is 1.1 kΩ at 1 W (2 x I R). (see
F
note)
Always make sure that the power is turned OFF before mounting,
removing, or wiring the Switch, or performing maintenance.
Note: A factor of 2 is applied because the permissible wattage of
the resistor must be twice as large as the required wattage.
Do not tighten the mounting ring excessively using pliers or a similar
tool. Excessive tightening may damage the mounting ring. (Tighten-
ing torque: 0.20 to 0.29 N⋅m)
Operating Environment
Ensure that dust, metal powder, or oil do not enter the interior of the
Switch.
Wiring
When wiring, use wires of a size appropriate for the applied voltage
and carry current. Perform soldering correctly under the conditions
given below. Using the Switch with the wires soldered incorrectly
may cause the terminals to become abnormally hot and cause a fire.
Using Microloads
Using a standard load switch for opening and closing a microload
circuit may cause wear on the contacts. Use the switch within the
operating range. (Refer to the diagram below.) Even when using mi-
croload models within the operating range shown below, if inrush
current occurs when the contact is opened or closed, it may cause
the contact surface to become rough, and so decrease life expec-
tancy. Therefore, insert a contact protection circuit where neces-
sary. 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 =
1. Hand soldering: At 30 W within 5 seconds.
2. Dip soldering: At 240°C within 3 seconds.
Wait for one minute after soldering before exerting any external
force on the solder.
Use a non-corrosive rosin liquid for the flux.
Perform wiring so that the wire sheaths do not come into contact
with the Switch. If this is unavoidable, use wires that can withstand
temperatures of 100°C min.
–4
0.5 x 10 /times indicates that the estimated malfunction rate is less
than 1/2,000,000 with a reliability level of 60%.
After wiring to the Switch has been completed, ensure an appropri-
ate insulation distance.
LED
The polarity of the LED is indicated on the back of the Switch. Wire
the LED correctly according to the polarity.
The built-in LED does not have a limiting resistor. Connect a limiting
resistor.

Make sure that the limiting resistor satisfies the characteristics of
