CAUTIONS FOR USE (Common for BJ, BS and BV types)
Notes for Turquoise Switches (BJ, BS, BV type)
Fastening of the switch body
1) Fasten the switch body onto a smooth surface using the
correct screw as shown in the chart below and tighten it with the
prescribed torque.
The switch case may deform depending on the type of screw
(screw head diameter, etc.), the size of the washer, and the use
or non-use of a washer. Therefore, please confirm the
appropriate torque of actual conditions. Also, it is recommended
that adhesive be applied to lock the screws to prevent loosening
of the screws. When doing so, please be careful not let any
adhesive get inside the switch.
2) Fixed pin type
To secure the switch unit, thermally crimp or press-fit the
mounting pins. If the pins are to be press-fitted, install a guide on
the opposite surface to the mounting pins to prevent them from
slipping out of position and developing play.
3) Be sure to maintain adequate insulating clearance between
each terminal and ground.
4) The positioning of the switch should be such that direct force
is not applied to the pushbutton or actuator in its free position.
The operating force to the pushbutton should only be applied in
a perpendicular direction.
5) The standard value of overtravel used should be within the
range of 70% to 100% of the rated OT value.
6) When soldering the BV type turquoise switch or the
immersion protected type of the BJ and BS type switches, the
sealing material sometimes forms a lump or bulge at the base of
the terminal or lead. Be sure to allow enough space for this
when attaching the switch.
Soldering operations
1) Manual soldering: Perform soldering in less than 3 seconds
with maximum 350°C iron. Care should be taken not to apply
force to the terminals during soldering. We recommend a
soldering iron with temperature adjustment in order to prevent
poor quality soldering.
Please consult us if you intend to use a soldering iron of 60 W or
higher.
2) Terminal portions should not be moved within 1 minute after
soldering.
Selection of the switch
Allow for up to ±20% variation of the specified characteristics
values to compensate for long term operational wear of the
switch in your design.
Cautions regarding use
1) When switching inductive loads (relays, solenoids, buzzers,
etc.), an arc absorbing circuit is recommended to protect the
contacts.
2) If switching of the contact is synchronized with the phase of
the AC power, reduced electrical life or welded contact may
occur. Therefore, test the switch while it is operating under actual
loads for this condition. If found, you may wish to take corrective
action in your design.
3) In the slow or high speed operating condition, the electrical
life might be greatly reduced depending upon the switching load.
Please consult us before use.
4) Using lever type in do not condition, there is the concern that
the flexible part may be impeded and return movement may not
be possible. In this situation take the following precautions:
Select a product of higher OF or use a leaf type lever.
Attach a protective cover to the lever.
5) If the leaf lever type switch is excessively pushed (pushed
further than the operational limit position) or switching is done at
high speed or is accompanied by the impact, the lever will break.
Please be careful. Also, be careful with the short roller lever type
ABV (BV) switch as improper return may result from pressing
too much.
Protection from dust, water and corrosive gas
1) The pin button and the space around the body cap Turquoise
switches are sealed with elastic material, the terminal portion is
integrally molded. This prevents dust entry and protects the
switch against corrosive gases. Wireleaded types are
recommended for applications subject to water or oil splash.
However, avoid soaking these immersion protected types in oil
or water, because those types are not of completely oil tight
construction.
2) Switch operation or rapid temperature change while water
droplets are on the switch may cause the water invasion inside
the switch because of breathing action on condensation.
Especially do not use switch in a bath.
If sources of silicon gas are existing in the vicinity of the switch
(silicon rubber, silicon oil, silicon coating, and silicon filler, etc.),
silicon gas (low molecular siloxane, etc.) will be emitted and it
will get into the product due to the permeability of the plastic.
If the switch is used or stored in such an environment, silicon
compound might generate on the contacts, cause the and faulty
contacting. Therefore, please do not use sources that can emit
silicon gas in the vicinity of the switch.
Do not use in areas where flammable or explosive gases from
gasoline and thinner, etc., may be present.

action contact mechanism that makes a specified motion with a
specified force to open/close a circuit, and an actuator outside
the enclosure (hereinafter referred to as the switch)
Actuator

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.)
Contact form
This refers to the
components
determining the type
of application which
make up the electrical
input/output circuits in
the contact.
Insulation resistance
Resistance between non-continuous terminals, each terminal

Actuation Force and Stroke
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.
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.
The figure at right
shows a typical
example of activation
and contact forces
varying with stroke.
In the vicinity of the
OP and RP, the
contact force is
diminished, causing
chatter and contact
bounce immediately
before or after
reversal. For this
reason, use the
switch while giving
due consideration to
this. This also causes
the snap action
switch to be sensitive
to vibration or shock.
Changes in Operating Characteristics
Exercise design care so that malfunctions will not occur if the
operating characteristics vary by as much as 20% from, rated
values.
<Example>
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
the allowable min. 0.15 N × (100%–20%) = 0.12 N
Mechanical Conditions for Type Selection
Actuator type should be selected according to activation
method, activation speed, activation rate, and activation
frequency.
1) An extremely slow activation speed may cause unstable
contact transfer, possibly resulting in contact failures or contact
fusion.
2) An extremely high activation speed may cause damage to
contacts or contact response failure.
Driving Mechanism
Use of a driving mechanism which will cause physical impact to
the actuator should be avoided.

TECHNICAL NOTES ON ELECTRICAL CHARACTERISTICS
CAUTIONS IN A CIRCUIT
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).
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
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.
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.
7) To prevent contact welding failure, be sure to use a serial
resistance for each capacitive load.
8) 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.

MOUNTING STATE AND ENVIRONMENT
Checking the insulation distance
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.
Fastening the snap-action switch body
See the Section “CAUTIONS FOR USE” for the individual
switch.
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.
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.
The following describes the case where the strictest tolerance
conditions are adopted.
Example: Hinge lever type FS switch
Soldering precautions
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.
Be careful not to apply force to the lead wires or the terminal
portions immediately after soldering.
The temperature setting and time conditions vary depending on
the product.
See the section “CAUTIONS FOR USE” for each product.
Avoid using in a silicon atmosphere
Avoid using organic silicon rubber, adhesives, sealing
compounds, oil, grease, and wires in a silicon atmosphere.
Please consult us when using under the following
conditions*:
1) Environments where hydrogen sulfide or other corrosive
gases are present.
2) Environments where gasoline, thinner or other flammable,
explosive gases are present.
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.
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.
(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.
(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.

Usage, storage, and transport conditions (except
turquoise switches)
During usage, storage, or transportation, avoid locations subject
to direct sunlight and maintain normal temperature, humidity,
and pressure conditions.
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. 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.
2) Humidity: The allowable temperature range differs for each
switch, so refer to the switch’s individual specifications.
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.)
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.
We reserve the right to modify without notice the
materials, internal components, and other parts to improve
product quality.
Handling precautions
When handling the switches, be careful not to drop them on the
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
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.

Shock Features
Pin plunger Small Small Large Out-
standing
Appropriate for linear short-stroke action. Pin plunger acts directly on snap
action mechanism, enabling high-precision positioning. Amount of movement
after operation is smallest among all of the actuators, however, so reliable
stopper is required.
Hinge lever Large Medium Small Possible
Little force required for operation. Appropriate for use with low-speed cams and
dogs; has large stroke.
Lever available in various shapes to fit operating unit.
Simulated roller
lever Large Medium Small Possible Tip of hinge lever is bent into a semi-circle, enabling use as a simple roller type.
Leaf lever Large Large Small Excellent Play in lever is used to assure maximum stroke. Construction provides for
space where lever is attached, for outstanding resistance to freezing.
Hinge roller lever Large Medium Small Possible
This is a hinge lever with a roller, and can be used with high-speed cams and
dogs.
The force required for pin plunger action is lighter than that of the lever, and the
stroke is longer.
