Safety Precautions

Refer to Safety Precautions for All Pushbutton Switches.

Precautions for Correct Use

• Twist the conductors through the terminal holes before soldering.

• To perform soldering on solder terminals, use a soldering iron with

a capacity of 60 W maximum and complete soldering within 5

seconds. Wait for one minute after soldering before exerting any

external force on the solder.

The Switch does not have a ground terminal.

• Do not perform wiring while power is being supplied to the Switch.

Do not touch the terminals or other charged parts of the Switch

while power is being supplied. Doing so may result in electric shock.

• After wiring the Switch, make sure that there is a suitable isolation

distance.

Mounting the Operation Unit

Panel Mounting

• The Operation Unit can be inserted and removed. Tighten the hexagonal nut while securing the Switch

• Mounting can be performed by inserting the slit of by holding it with your fingers. Tighten the hexagonal
