Safety Precautions

Refer to Safety Precautions for All Pushbutton Switches.

Operation Unit Mounting

VAQ-4@-K

•The Operation Unit can be inserted and removed.

•Mounting can be performed by inserting the slit of the Operation

Unit into the mounting screw of the Switch.

•Mounting force: 39.2 N max.

•Removing strength: 22.5 N min.

VAQ-4@-L

•The Operation Unit is screwed in.

•Mounting can be performed by inserting the M3 screw of the

Operation Unit into the flange of the Switch.

•Tighten the Operation Unit to a torque of 0.20 to 0.39 N·m.

2VAQ-4@

VAQR-4@

•The Operation Unit is screwed in.

•Mounting can be performed by inserting the M3 screw of the

Operation Unit into the metal flange of the Switch.

•Tighten the Operation Unit to a torque of 0.20 to 0.39 N·m.

Mounting

•Tighten the nut to a torque of 0.49 to 0.78 N·m.

•Do not perform wiring with power 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, ensure an appropriate insulating distance.

Wiring

•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.

•For connection with tab terminals, gently insert receptacles for

#187 tabs in the terminal push-out direction.

The Switch does not have a ground terminal.
