Safety Precautions

Refer to Safety Precautions for All Pushbutton Switches.

WARNING

Do not apply a voltage between the incandescent

lamp and the terminal that is greater than the rated

voltage. If the incandescent lamp is broken, the

Operation Units may pop out.

LED

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

not required.

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

Always turn OFF the power and wait for 10 minutes

before replacing the incandescent lamp. If the lamp is replaced

immediately after the power is turned OFF, the remaining heat

may cause burns.

the following conditions:

Base: BA9S/13

Overall length: 26 mm max.

Power consumption: 2.6 W max.

Others

x If the panel is to be finished with coating, etc., make sure that the

panel meets the specified dimensions after the coating.

x Do not subject the Switch to extreme shock or vibration. Doing so

will cause malfunctions and damage to the Switch.

Using the Microload

Precoutions for Correct Use

Mounting

x 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.

x 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 more than necessary using tools

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

ring.

x 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% (O 60) (conforming to JIS C5003).

The tightening torque is 0.98 to 1.96 N·m.

x Recommended panel thickness: 1 to 5 mm.

Wiring

The equation, O 60 = 0.5 x 10^ꢀ6/operations indicates that the

estimated malfunction rate is less than 1/2,000,000 operations with

a reliability level of 60%.

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

terminal is positive.

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

square washer.

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

x Solid wires, stranded wires, and crimp terminals can be connected

to the Switch.

Caution

Do not apply a voltage between the incandescent lamp

and the terminal that is greater than the rated voltage.

Doing so may damage the lamp or LED and cause the

Operation Unit to pop out.

Always turn OFF the power and wait for 10 minutes

before replacing the incandescent lamp. If the lamp is

replaced immediately after the power is turned OFF,

the remaining heat may cause burns.

Precautions for Correct Use of Pushbutton Switches

●For the individual precautions for a Switch, refer to the precautions in the section for that Switch.

Electrical Characteristics

1. Operating Load

All the performance ratings given are for operation under the following

conditions unless otherwise specified.

Inductive load: A minimum power factor of 0.4 (AC) and a maximum

time constant of 7 ms (DC)

Lamp load: An inrush current 10 times higher than the steady-state

current

x The switching load capacity of the Switch greatly varies between

AC and DC. Always be sure to apply the rated load. The control

capacity will drastically drop if it is a DC load. This is because a DC

load has no current zero-cross point, unlike an AC load. Therefore,

if an arc is generated, it may continue for a comparatively long time.

Furthermore, the current direction is always the same, which

results in a contact relocation phenomena whereby the contacts

easily stick to each other and do not separate when the surfaces of

the contacts are uneven.

Motor load: An inrush current 6 times higher than the steady-state

current

Note: Inductive loads can cause problems especially in DC circuitry. Therefore,

it is essential to know the time constants (L/R) of the load.

x

Some types of load have a great difference between normal current

and inrush current. Make sure that the inrush current is within the

permissible value. The greater the inrush current in the closed circuit

is, the greater the contact abrasion or shift will be. Consequently,

contact weld, contact separation failures, or insulation failures may

result. Furthermore, the Switch may be broken or damaged.

2. Load Connections

Do not contact a single Switch to two power supplies that are different

in polarity or type.

Connection of Different Polarities

x

If the load is inductive, counter-electromotive voltage will be generated.

The higher the voltage is, the higher the generated energy will be,

which will increase the abrasion of the contacts and contact relocation

phenomena. Be sure to use the Switch within the rated conditions.

The power supply may short-circuit if the loads are connected in the

way shown in the "incorrect" example below.

Even in the "correct" example, note that the insulation performance of

the switch may deteriorate and the switch life may be shortened

because loads are connected to both contacts.

t

x Approximate control capacities are given in ratings tables, but

these alone are insufficient to guarantee correct operation. For

special types of load, with unusual switching voltage or current

waveforms, test whether correct operation is possible with the

actual load before application.

Connection of Different Power Supplies

The DC and AC power may be mixed for the circuit shown below.

Incorrect

x When switching for microloads (voltage or current), use a Switch

with microload specifications. The reliability of silver-plated

contacts, which are used in Switches for standard loads, will be

insufficient for microloads.

When switching microloads or very high loads that are beyond the

switching capacity of the Switch, connect a relay suitable for the load.

3. Contact Protective Circuit

Apply a contact protective circuit to extend the contact life, prevent

noise, and suppress the generation of carbide or nitric acid. Be sure

to apply the contact protective circuit correctly, otherwise an adverse

effect may occur. The following provides typical examples of contact

protective circuits. If the Limit Switch is used in an excessively humid

location for switching a load that easily generates arcs, such as an

inductive load, the arcs may generate NOx, which will change into

HNO³if it reacts with moisture. Consequently, the internal metal parts

may corrode and the Limit Switch may fail. Be sure to select the ideal

contact preventive circuit from the following.

The values may change according to the

characteristics of the load. The capacitor

suppresses the spark discharge of current

when the contacts are open. The resistor

limits the inrush current when the contacts

are closed again. Consider the roles of the

capacitor and resistor and determine ideal

capacitance and resistance values through

testing. Basically, use a capacitor with a

dielectric strength between 200 and 300 V.

When AC is switched, make sure that the

capacitor has no polarity.

4. Switching

x

Do not use the Switch for loads that exceed the rated switching capacity or other

contact ratings. Doing so may result in contact weld, contact separation failures,

or insulation failures. Furthermore, the Switch may be broken or damaged.

x Do not apply excessive or incorrect voltages to the Switch or

incorrectly wire the terminals. Otherwise, the Switch may not

function properly and have an adverse effect on external circuitry.

Furthermore, the Switch itself may become damaged or burnt.

x Do not use the Switch in locations where flammable or explosive

gases are present. Otherwise switching arcs or heat radiation may

cause a fire or explosion.

x Do not drop or disassemble the Switch, otherwise it may not be

capable of full performance. Furthermore, it may be broken or

burnt.

x Do not touch the charged switch terminals while power is supplied,

otherwise an electric shock may be received.

x The life of the Switch varies greatly with switching conditions.

Before using the Switch, be sure to test the Switch under actual

conditions. Make sure that the number of switching operations is

within the permissible range. If a deteriorated Switch is used

continuously, insulation failures, contact weld, contact failures,

switch damage, or switch burnout may result.

Mechanical Conditions

Operating Force and Operating Method

Mounting

x Fingertip operation is an important feature of Pushbutton Switches.

In terms of Switch operation, Pushbutton Switches differ greatly

from detection switches such as Microswitches. Operating the

Switch using a hard object (e.g., metal), or with a large or sudden

force, may deform or damage the Switch, resulting in faulty or rough

operation, or shortening of the Switch life. The strength varies with

the size and construction of the Switch. Use the appropriate Switch

for the application after confirming the operating method and

operating force with this catalog.

x Switches can be broadly divided into two categories according to

mounting method: panel-mounting models and PCB-mounting

models. Use the appropriate model for the mounting method

required. Basically, panel-mounting Switches can withstand a

greater operating force than PCB-mounting Switches. If, however,

the panel thickness or the panel-cutout dimensions are not suitable

for the Switch, it may not be able to withstand the normal operating

force. With continuous mounting in particular, select a panel of a

thickness that is easily sufficient to withstand the total operating

force.

Hammer

x Panel-mounting Switches can be divided into two categories

according to the mounting method: snap-in mounting models and

screw-mounting models. Snap-in mounting Switches are held in

place with the elasticity of resin or a metal leaf spring. Do not

attempt to modify the spring after mounting. Doing so may result in

faulty operation or damage the mounting structure. Mount screw-

mounting models using the screws and nuts provided (or

individually specified). Tighten the screws to the specified torque.

Mounting with different screws or nuts, or tightening beyond the

specified torque may result in distortion of the inside of the case or

damage to the screw section.

Do not apply

excessive or

sudden force.

x The pushbutton surface is composed of resin. Therefore, do not

attempt to operate the pushbutton using a sharp object, such as a

screwdriver or a pair of tweezers. Doing so may damage or deform

the pushbutton surface and result in faulty operation.

Screwdriver

x Subjecting the Switch to severe vibrations or shock may result in

faulty operation or damage. Also, many of the Switches are

composed of resin so contact with sharp objects may result in

damage to the surface. This kind of damage may spoil the

appearance of the Switch or result in faulty operation. Do not throw

or drop the Switch.

Mounting Precautions

Wiring

• Perform hand soldering using the appropriate soldering iron.

•

Perform wiring so that the lead wires will not be caught on other objects

as this will cause stress on the Switch terminals. Wire the Switch so

that there is slack in the lead wires and fix lead wires at intermediate

points. If the panel to which the Switch is mounted needs to be opened

and closed for maintenance purposes, perform wiring so that the

opening and closing of the panel will not interfere with the wiring.

Terminal

Perform soldering for

between 3 to 5 s with

a suitable soldering iron.

Small-capacity

soldering iron

time

Large-capacity

Lead wire

• With the exception of PCB-mounting Switches, when performing

hand soldering, hold the Switch so that the terminals point

downwards so that flux does not get inside the Switch.

• Leave a gap of at least 1 mm between the soldered parts and the

surface of the case so that flux does not get inside the Switch.

Case

Terminal

Solder

• With miniature Switches, the gap between the terminals is very

narrow. Use protective or heat-absorbing tubes to prevent burning

of the wire sheath or shorting.

Lead wire

• When applying flux using a brush, use a sponge soaked in flux as

shown below. Do not apply more than is necessary. Also, apply the

flux with the PCB inclined at an angle of less than 80° so that flux

does not flow onto the mounting surface of the Switch.

• There are two methods for soldering the Switch: hand soldering and

automatic soldering. In addition, automatic soldering itself can be

divided into two types : dip soldering and reflow soldering. Use the

soldering method appropriate for the mounting method.

Technical Guide for Pushbutton Switches

• Do not place PCBs that have had flux applied or have been

Storage

soldered on top of each other. Otherwise, the flux on the PCBs

solder surface may stain the upper part of the Switch or even

permeate the inside of the Switch and cause contact failure.

Be sure to insert a special PCB stocker.

• When the Switch is left unused or stored for long periods, the

ambient conditions can have a great effect on the condition of the

Switch. In certain environments, leaving the Switch exposed may

result in deterioration (i.e., oxidation, or the creation of an oxide

film) of the contacts and terminals, causing the contact resistance

to increase, and making it difficult to solder the lead wires.

Therefore, store in a well-ventilated room, inside, for example, a

non-hygroscopic case, in a location where no corrosive gases are

present.

Flux

Do not place PCBs

with solder or flux on

top of each other.

• When performing soldering with a dip soldering bath, ensure that

the flux does not reach a higher level than the PCB.

• If the Switch is stored in a location where it will be exposed to direct

light, colored resin in the colored plate may fade. Therefore, do not

store the Switch in locations where it will be exposed to direct light.

• Flux is especially likely to rise up at the edges of the PCB. If the

Switch is mounted near the edge of the PCB, create a gap between

the edge by using a split PCB, and insert the PCB in the soldering

bath so that the edge that is farthest from the Switch enters the bath

first.
