Safety Precautions

Refer to Safety Precautions for All Pushbutton Switches.

CAUTION

Do not apply a voltage higher than the maximum

rated operating voltage between the lamp terminals,

as there is a risk that the incandescent lamp or LED

lamp will be damaged, and the Pushbutton will be

ejected.

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

microload 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

expectancy. Therefore, insert a contact protection circuit where

necessary. 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 x 10⁻⁶/times indicates that the estimated

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

60%.

When replacing the incandescent lamp, first turn OFF

the power supply, and then wait 10 minutes before

performing replacement, as the lamp is still hot

immediately after the power is turned OFF, so there

is a risk of burns.

Precautions for Correct Use

Mounting

• To prevent electric shock or a fire, always make sure that the power

is turned OFF before mounting, removing, or wiring the Switch, or

performing maintenance.

Do not tighten the mounting ring excessively using pliers or a similar

tool. Excessive tightening may damage the mounting ring.

(Tightening torque: 0.20 to 0.39 N·m {20 gf to 40 gf})

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.

1. Soldering iron tip temperature: 350°C max. within 3 seconds.

2. Dip soldering: At 350°C within 3 seconds.

Wait for one minute after soldering before exerting any external

force on the solder.

LED

• 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.

• After wiring to the Switch has been completed, ensure an

appropriate insulation distance.

• Resistance to limit the LED current is provided internally and so an

external resistance is not required.

Application

Mounting and Replacing the Pushbutton

(1) Mounting Direction for the Pushbutton/Display and Lamp

Lighted Pushbutton Switch

• Insert the Lamp (incandescent lamp or LED lamp) into the

Pushbutton so that the lamp guide fits into the wider gap between

the projections on the Pushbutton.

Panel Mounting

• Insert the Switch from the front of the panel. Mount the mounting

nut from the terminal end of the Switch and tighten it.

• There are projections on the terminal end of the Switch which may,

depending on the orientation, block the nut. In this case, turn the nut

until it is possible to mount it. Tighten the nut to a torque between

0.20 and 0.39 N·m.

• If soldering is used, mount the mounting nut first. Lead wires and

mounds of solder may make it impossible to mount the nut after

soldering.

• With Indicators, the Lamp is inserted facing the opposite direction

(i.e., at 180°) to that for Lighted Pushbutton Switches.

Mounting the Insulation Cover

• After securing the Switch to the panel using the mounting nut, pass

the lead wires through the holes in the Insulation Cover and then

perform 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.

Note: 1. The mounting direction for Indicators is 180° to that for Lighted

Pushbutton Switches. Be sure to insert the Legend Plate and other

parts with the correct orientation.

2. If the terminals of the Lamp become bent, it may be impossible to fit

them into the lamp terminal holes. Ensure that the terminals are

straight when they are inserted.

• After wiring is completed, mount the Insulation Cover by pushing it

into the Switch.

3. Take particular care about the mounting direction with the round

models (A3CT).

Mounting the Dust Cover

1. The Dust Cover separates into 2 parts: the cap and the mounting

frame.

2. Insert the Switch into the mounting frame. (Align the lock

projection with the recess on the mounting frame.)

3. Insert the Switch in the state described in step 2 into the panel.

(Align the lock protrusion on the mounting frame with the hole in

the panel.)

4. Mount the mounting nut from the back of the panel and tighten it.

5. Insert the cap into the mounting frame. Ensure that the entire

perimeter of the cap is properly inserted into the mounting frame

by pressing down on the cap from different directions.
