Safety Precautions

Be sure to read the precautions for all pushbutton switches in the

Pushbutton Switches Group Catalog (Cat. No. X018).

!CAUTION

■ Precautions for Correct Use

Mounting

• Always make sure that the power is turned OFF before wiring the

Switch. Also, do not touch the terminals or other current-carrying

ports while power is being supplied. Electric shock may occur.

• Do not tighten the mounting ring more than necessary using tools

such as pointed-nose pliers. Doing so will damage the mounting

ring. The tightening torque is 0.98 to 1.96 N·m.

• Recommended panel thickness: 1 to 5 mm.

Wiring

• When DC-specific LEDs are used, wire the Switch so that the X1

terminal is positive.

• Terminal screws must be Phillips or slotted M3.5 screws with a

square washer.

• The tightening torque is 1.08 to 1.27 N·m.

• Single wires, stranded wires, and crimp terminals can be

connected to the Switch.

• Applicable Wiring Materials:

Solid wire: 1.6 mm dia.

• After wiring the Switch, maintain an appropriate clearance and

creepage distance.

Operating Environment

• The IP65 model is designed with a protective structure so that it will

not sustain damage if it is subjected to water from any direction to

the front of the panel.

LEDs

• The LED current-limiting resistor is built-in, so internal resistance is

not required.

• If commercially available LEDs are used, select the ones that meet

the following conditions:

Base: BA9S/13

@

Overall length: 26 mm max.

Power consumption: 2.6 W max.

Using the Microload

• Contact failure may occur if a Switch designed for a standard load

is used to switch a microload. Use Switches within the application

ranges shown in the following graph. Even within the application

range, 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 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,

malfunction rate is less than 1/2,000,000 with a reliability level of

60%.

Others

• If the panel is to be coated, make sure that the panel meets the

specified dimensions after coating.

• Due to the structure of the Switch, severe shock or vibration may

cause malfunctions or damage to the Switch. Also, most Switches

are made from resin and will be damaged if they come into contact

with sharp objects. Particularly scratches on the Operation Unit

may create visual and operational obtrusions. Handle the Switches

with care, and do not throw or drop them.

Do not apply a voltage exceeding the rated voltage across the

incandescent lamp terminals.

The lamp may be destroyed and the operation unit may fly out.
