CAUTIONS FOR USE

■ Mounting panel

2) The terminals should be connected in

such a way that they are not under

constant stress from the connecting

wires.

3) Terminal material is copper alloy which

may discolor due to ﬁnger’s oil or after a

long time. But that discoloration does not

effect actual performance.

■ Environment

Mount the switch with the hole cutting

dimensions shown in the dimensions.

Please contact us if you are considering

using a panel of other than the

recommended size and shape.

■ Regarding fastening lead wires to

terminals

Avoid using and storing these switches in

a location where they will be exposed to

corrosive gases, silicon, or high dust

levels, all of which can have an adverse

effect on the contacts.

■ Take care not to drop the product as

it may impair perfomance.

1) When connecting the tab terminals,

use a .250 Quick-connect and insert the

terminals straight in. If they are skewed,

the terminals will require excessive

insertion force. In addition, there is some

variation in the insertion force required for

different receptacles from different

manufacturers, so conﬁrm how much

force is needed under actual conditions.

Do not solder wires onto tab terminals.

■ Resistance to chemicals

■ For general precautions for

operation switches, please visit our

website.

To clean the switch unit, use a neutral

detergent diluted with water. Do not use

acidic or alkaline solvents as they may

damage the switch. Furthermore, be

careful not to get any of the detergent

solution inside of the switch while

cleaning it.

TECHNICAL TERMINOLOGY

■ Rated values

■ Shock resistance

Values indicating the characteristics and performance guarantee

standards of the switches. The rated current and rated voltage,

for instance, assume speciﬁc conditions.

Max. shock value where a closed contact does not open for

longer than a speciﬁed time due to shocks during use of the

switches.

end of mechanical life (or electrical life).

■ Mechanical life

■ Temperature rise value

The service life when operated at a preset operating frequency

without passing electricity through the contacts.

This is the maximum temperature rise value that heats the

terminal portion when the rated current is ﬂowing through the

contacts.

■ Dielectric strength

Threshold limit value that a high voltage can be applied to a

predetermined measuring location for one minute without

causing damage to the insulation.

■ Actuator strength

When applying a static load for a certain period on the actuator

in the operation direction, this is the maximum load it can

withstand before the switch loses functionality.

■ Insulation resistance

This is the resistance value at the same place the dielectric

■ Terminal strength

strength is measured.

When applying a static load for a certain period (in all directions

if not stipulated) on a terminal, this is the maximum load it can

withstand before the terminal loses functionality (except when

the terminal is deformed).

■ Contact resistance

This indicates the electrical resistance at the contact part.

Generally, this resistance includes the conductor resistance of

the spring and terminal portions.

■ Vibration resistance

Vibration range where a closed contact does not open for longer

than a speciﬁed time due to vibrations during use of the snap-

action switches.

Technical Terminology & Cautions for Use

TYPES OF LOAD

■ Resistance load

■ Motor load

Resistance load is a power factor of 1 (cosφ = 1) where the load

is only for the resistance portion. The displayed switch rating

indicates the current capacity when using AC current.

Contacts may adhere due to the starting current at the start of

motor operation which is three to eight times the steady-state

current. Although it differs depending on the motor, since a

current ﬂows that is several times that of the nominal current,

please select a switch taking into consideration the values in the

table below. To make the motor rotate in reverse, use an ON-

OFF-ON switch and take measures to prevent a multiplier

current (starting current + reverse current) from ﬂowing.

■ DC load

Differing from AC, since the direction of current is ﬁxed for DC,

the continuous arc time lengthens when the same voltage is

applied.

Motor type

Type

Starting current

■ Incandescent lamp load

Three-phase

induction motor

Approx. 5 to 8 times current listed on

nameplate

Squirrel-cage

Since an inrush current of 10 to 15 times the rated current ﬂows

for an instant when the switch is turned on for the lamp,

adhesion of the contacts may occur. Therefore, please take into

consideration this transient current when selecting a switch.

Approx. 6 times current listed on

nameplate

Split-phase-start

Capacitor-start

Repulsion-start

Single-phase

induction motor

Approx. 4 to 5 times current listed on

nameplate

Approx. 3 times current listed on

nameplate

■ Induction load

Since arc generation due to reverse voltage can cause contact

failure to occur when there is an induction load (in relays,

solenoids and buzzers, etc.), we recommend you insert a

suitable spark quenching circuit (see ﬁgure below).

A current that is approximately two times that of the starting

current will ﬂow when reverse rotation is caused during

operation. Also, when using for a load that will cause transient

phenomena such as when operating the motor in reverse

rotation or switching the poles, an arc short (circuit short) may

occur due to the time lag between poles when switching. Please

be careful.

■ Capacitor load

In the case of mercury lamps, ﬂorescent lamps and the

capacitor loads of capacitor circuits, since an extremely large

inrush current ﬂows when the switch is turned on, please

measure that transient value with the actual load and then either

use the product keeping within the range of the rated current or

after verifying the actual load.

Technical Terminology & Cautions for Use

CAUTIONS FOR USE

■ Environment of use

■ Wiring

1) Please consult us when using under the following conditions:

• Environments where hydrogen sulﬁde or other corrosive gases

are present.

1) When using a PC board terminal switch as soldering

terminals, use thin lead wires and be sure to wind them on the

terminals before soldering.

• Environments where gasoline, thinner or other ﬂammable,

explosive gases are present.

• Dusty environments (for non-seal type snap action switches).

• Use in environments not in the prescribed temperature or

humidity range.

2) Cautions when soldering

Perform soldering quickly in accordance with the speciﬁed

conditions. Be careful not to let ﬂux ﬂow into the product. When

no instruction is speciﬁed, use a soldering iron with a tip

temperature of 350°C or lower and complete soldering within

ﬁve seconds. Do not pull on the lead wires immediately after

soldering. Wait some time before verifying.

• Places with low air pressure.

2) Unless speciﬁed the product will not be constructed to

withstand water, oil or explosions. Please inquire if you intend to

use the product in special applications.

■ Others

■ Usage, storage, and transport conditions

1) During usage, storage, or transportation, avoid locations

subject to direct sunlight and maintain normal temperature,

humidity, and pressure conditions.

2) The allowable speciﬁcations for environments suitable for

usage, storage, and transportation are given below.

(1) Temperature: The allowable temperature range differs for

each switch, so refer to the switch’s individual speciﬁcations.

(2) Humidity: 5 to 85% R.H.

1) Failure modes of switches include short-circuiting, open-

circuiting and temperature rises. If this switch is to be used in

equipment where safety is a prime consideration, examine the

possible effects of these failures on the equipment concerned,

and ensure safety by providing protection circuits or protection

devices. In terms of the systems involved, make provision for

redundancy in the design and take steps to achieve safety

design.

2) The ambient operating temperature (and humidity) range

quoted is the range in which the switch can be operated on a

continuous basis: it does not mean that using the switch within

the rating guarantees the durability performance and

environment withstanding performance of the switch. For details

on the performance guarantee, check the speciﬁcations of each

product concerned.

(3) Pressure: 86 to 106 kPa

The humidity range varies with the temperature. Use within the

range indicated in the graph below.

(The allowable temperature depends on the switch.)

Humidity, %R.H.

3) Even if 2-pole, 3-pole or 4-pole switches are used as single-

pole switches in order to increase contact reliability, please keep

the maximum current no higher than the rated value.

4) If there is the possibility of a short between poles, please use

an in-phase circuit as shown below or provide a spare pole.

Tolerance range

(Avoid freezing when

used at temperatures

lower than 0°C 32°F)

Temperature, °C °F

Heteropolar circuit

• Condensation will occur inside the switch if there is a sudden

change in ambient temperature when used in an atmosphere of

high temperature and high humidity. This is particularly likely to

happen when being transported by ship, so please be careful of

the atmosphere when shipping. Condensation is the

phenomenon whereby steam condenses to cause water

droplets that adhere to the switch when an atmosphere of high

temperature and humidity rapidly changes from a high to low

temperature or when the switch is quickly moved from a low

humidity location to one of high temperature and humidity.

Please be careful because condensation can cause adverse

conditions such as deterioration of insulation, coil cutoff, and

rust.

Good example (1)

Load 2

In-phase circuit

Good example (2)

Load 1

Spare pole

Load 2

• Condensation or other moisture may freeze on the switch when

the temperatures is lower than 0°C 32°F. This causes problems

such as sticking of movable parts or operational time lags.

• The plastic becomes brittle if the switch is exposed to a low

temperature, low humidity environment for long periods of time.

• Storage for extended periods of time (including transportation

periods) at high temperatures or high humidity levels or in

atmospheres with organic gases or sulﬁde gases may cause a

sulﬁde ﬁlm or oxide ﬁlm to form on the surfaces of the contacts

and/or it may interfere with the functions. Check out the

atmosphere in which the units are to be stored and transported.

• In terms of the packing format used, make every effort to keep

the effects of moisture, organic gases and sulﬁde gases to the

absolute minimum.

5) Be careful not to drop the product as this may cause loss of

functionality.

6) Do not apply an unreasonable vertical force against the

direction of operation of the product.

7) Use your hand to operate the actuator.

(Operation using a tool such as a screwdriver or hammer can

cause breakdown.)
