■ Insulation resistance

Resistance between non-continuous terminals, each terminal

and other exposed metal parts and between each terminal and

ground.

■ Rated values

Values indicating the characteristics and performance guarantee

standards of the snap-action switches. The rated current and

rated voltage, for instance, assume speciﬁc conditions (type of

load, current, voltage, frequency, etc.).

■ Dielectric

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

predetermined measuring location for one minute without

causing damage to the insulation.

■ Mechanical life

The service life when operated at a preset operating frequency

without passing electricity through the contacts. (The life test is

performed at a switching frequency of 60 times/minute and

operating speed of 100 mm/second at the regular cam.)

■ Contact resistance

This indicates the electrical resistance at the contact part.

Generally, this resistance includes the conductor resistance of

the spring and terminal portions.

■ Electrical life

The service life when the rated load is connected to the contact

and switching operations are performed. (The life test is

performed at a switching frequency of 20 times/minute and

operating speed of 100 mm/second at the regular cam.)

■ Vibration resistance

Malfunction vibration ... 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.

■ Shock resistance

Shock durability ... Shock range where the mechanical shocks

received during snap-action switches transport and installation

do not damage the parts or harm the operating characteristics.

Malfunction shock ... Shock range where a closed contact does

not open for longer than a speciﬁed time due to shocks during

use of the snap-action switches.

TECHNICAL NOTES ON MECHANICAL CHARACTERISTICS

■ Actuation Force and Stroke

■ Changes in Operating Characteristics

Adequate stroke setting is the key to high reliability. It is also

important that adequate contact force be ’maintained to ensure

high reliability. For a normally closed (NC) circuit, the driving

mechanism should be set so that the actuator is normally in the

free position. For a normally open (NO) circuit, the actuator

should be pressed to 70% to 100% of the speciﬁed stroke to

absorb possible errors.

Exercise design care so that malfunctions will not occur if the

operating characteristics vary by as much as 20% from, rated

values.

In the OF max. 0.98N speciﬁcation for FS snap-action switches,

the allowable max. is 0.98 N × (100%+20%) = 1.18 N

In the RF min. 0.15 N min. speciﬁcation

If the stroke is set too close to the operating point (OP), this may

cause unstable contact, and in the worst case may cause

actuator damage due to inertia of the drive mechanism. It is

advisable that the stroke be adjusted with the mounting plate or

driving mechanism.

Technical Terminology & Cautions for Use

TECHNICAL NOTES ON ELECTRICAL CHARACTERISTICS

1) The snap-action switch is designed for AC operations.While it

has small contact gaps and no arc absorber, it may be used for

low-capacity DC operations.

Please refer to the rating of each products

2) For applications with very small switching voltage or current,

choose the low-level load type (Au contact).

beginning of use. However, as the contact surfaces develop ﬁlms

with time, the ﬁlm may not be broken by the switching operation,

causing a conduction failure. Therefore, please choose the Au

contact type for switching a load of 0.1 A or below.

4) Application to Electronic Circuits

• The snap-action switch contacts can sustain bounce or chatter

when closed. Bounce or chatter can cause noise or pulse count

errors when the snap action switch is used in electronic circuits.

• If contact bounce or chatter poses problems in the vicinity of

the OP and RP, use a suitable absorption network, such as a C/

R network.

Small current and voltage application range (Au contact)

5) Check the surge current, normal current and surge duration.

6) Contact resistance given in performance speciﬁcations is

measured with a voltage drop method using 6 to 8 V DC, 1 A

(except for low-level load type). Contact resistance across COM

and NC terminals is measured in the free position, while contact

resistance across COM and NO terminals is measured in the

total travel position.

8) To prevent contact welding failure, be sure to use a serial

resistance for each capacitive load.

9) If snap-action switch operation is synchronized with the AC

supply phase, this may cause: shortened electrical life, contact

fusion failure, contact transfer, or other reliability problems.

3) When selecting a contact type of a snap-action switch to be

used for low-level load switching, the following should be noted.

Silver contacts’ surfaces are prone to be oxidized and form a

sulﬁde ﬁlm. The switch operates with no problems at the

Technical Terminology & Cautions for Use

MOUNTING STATE AND ENVIRONMENT

■ Checking the insulation distance

■ Soldering precautions

After mounting and wiring, check the insulation distance

between terminals and the ground. If the insulation distance is

inadequate, mount insulating material between as required.

For manual soldering, lay the terminals ﬂat (horizontal with the

ground) and quickly perform the soldering operation using a

soldering iron with the appropriate heat capacity and the proper

amount of solder. Take care that the ﬂux does not ﬂow into the

switch interior by using a ventilation fan to discharge ﬂux gas

and to prevent contact of the switch body with the soldering iron

tip.

■ Fastening the snap-action switch body

See the Section “CAUTIONS FOR USE” for the individual

switch.

Be careful not to apply force to the lead wires or the terminal

portions immediately after soldering.

■ Position adjustment with effector

1) The effector should be positioned so that direct force is not

applied to the plunger or actuator in its free position. The

operating force to the plunger should only be applied in a

perpendicular direction.

2) Note that the use of the switch as a stopper may cause an

operational problem.

The temperature setting and time conditions vary depending on

the product.

See the section “CAUTIONS FOR USE” for each product.

Soldering iron tip

■ Switch installation position

• Basically, the switch should be installed so that the object to

press the switch’s plunger or lever can press it down to 70 to

100% of OT of the switch. When determining the position, the

tolerance of OP (Operating Position) and other factors should be

taken into account.

Wrong

Correct

The following describes the case where the strictest tolerance

conditions are adopted.

■ Avoid using in a silicon atmosphere

• Example: Hinge lever type FS switch

Avoid using organic silicon rubber, adhesives, sealing

compounds, oil, grease, and wires in a silicon atmosphere.

Reference values: OP = 8.8 0.8mm

PT = max. 2.8mm

■ Please consult us when using under the following

conditions*:

1) Environments where hydrogen sulﬁde or other corrosive

OT = min. 1.2mm

FP

gases are present.

OP

PT

2) Environments where gasoline, thinner or other ﬂammable,

explosive gases are present.

TTP

OT

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

4) The perpendicular operating speed exceeds the allowable

operating speed.

5) Switching between different poles.

6) Use in environments not in the prescribed temperature or

humidity range.

(1) When the switch is not pressed

The object to press the lever should not be in contact with

the lever.

For this purpose, the object should be at a distance from

the switch father than the maximum FP (Free Position)

value.

FP max = OP max + PT max = 9.6 + 2.8 = 12.4 mm max

The object should be at a distance of 12.4 mm or more

from the mounting hole.

■ Storage precautions

To prevent discoloration due to sulfurization of the terminals

(silver- plated), store the switches in a polyethylene bag or other

suitable airtight container.

(2) Depressed position

The plunger/lever should be pressed down to 70% or

more of OT (Over Travel). Therefore, the depressed

position should be calculated based on the minimum

value of OP (Operating Position) and the 70 and 100% of

the OT value.

OP min - 70% of OT = 8.0 - 0.84 = 7.16 mm

OP min - 100% of OT = 8.0 - 1.2 = 6.80 mm

The plunger/lever should be pressed down to the position

of 6.80 to 7.16 mm from the mounting hole.

Technical Terminology & Cautions for Use

■ Usage, storage, and transport conditions

During usage, storage, or transportation, avoid locations subject

to direct sunlight and maintain normal temperature, humidity,

and pressure conditions.

■ We reserve the right to modify without notice the

materials, internal components, and other parts to improve

product quality.

The allowable speciﬁcations for environments suitable for usage,

storage, and transportation are given below.

■ Handling precautions

When handling the switches, be careful not to drop them on the

1) Temperature: The allowable temperature range differs for

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

addition, when transporting or storing switches while they are

tube packaged, there are cases when the temperature may differ

from the allowable range. In this situation, be sure to consult the

individual speciﬁcations.

ﬂoor since this may damage them.

* Select contact sulfurization (clipping) prevention products (FS and Au-clad double

layer contacts) for use with extremely small loads or an environment-resistant

Turquoise switch.

■ Others

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

3) Pressure: 86 to 106 kPa

The humidity range varies with the temperature. Use within the

range indicated in the graph below.

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.

(The allowable temperature depends on the switch.)

• 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.

• 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.
