CAUTIONS FOR USE
■ Soldering conditions
• The application of excessive heat upon
the switch when soldering can cause
degradation of switch operation.
Therefore, be sure to keep within the
conditions given below.
• Manual soldering: Use soldering irons
(max. 350°C, within 3 seconds) capable
of temperature adjustment. This is to
prevent deterioration due to soldering
heat. Care should be taken not to apply
force to the terminals during soldering.
(More than one second interval is
required to apply heat at each terminal.)
Please consult us if you intend to use a
soldering iron that exceeds 60 W.
■ Mounting
• To secure the wire leads type switch,
please use M3 small screws on a flat
surface and tighten using a maximum
torque of 0.29 N·m.
Be sure to verify the quality under actual
conditions of use because the switch
plastic might be deformed according to
that the kind of the screw (size of screw
head etc.), the diameter of the washer
and the presence of washer. And use of
adhesive lock is recommended to prevent
loosening of the screws. When using an
adhesive, care should be taken not to
invade the adhesive into the switches.
• Be sure to maintain adequate insulating
clearance between each terminal and
ground.
• The positioning of the switch should be
such 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.
• When slanted press operation is applied
to pin plunger type switches by an
operation cam, the endurance life may
greatly vary depending on the use of
grease for sliding, operation angle,
operation speed, operation frequency,
press amount of the pin plunger, cam
material, cam shape, cam surface
condition, etc. Therefore fully verification
by using the actual equipment in advance
should be implemented.
• After mounting please make sure no
pulling load will be applied to the switch
terminals.
■ Cautions regarding the circuit
• In order to prevent malfunction in set
devices caused by bounce and chattering
during the ON-OFF switch operation,
please verify the validity of the circuit
under actual operating conditions and
temperature range.
• When switching inductive loads (relays,
solenoids, buzzers, etc.), it is
recommended that contact protection
element such as diode, varistor, etc., is
introduced to prevent contact failure
caused by electric discharge.
■ Please verify under actual
conditions.
• Please be sure to conduct quality
verification under actual operating
conditions in order to increase reliability
during actual use.
■ Selection of switch
• Please make your selection so that
there will be no problems even if the
operating characteristics vary up to ±20%
from the standard values.
■ Oil-proof and chemical-proof
characteristics
• Do not use alcohol-based solvents.
• The rubber cap swells when exposed to
oil and chemicals. The extent of swelling
will vary widely depending on the type
and amount of oil and chemicals.
Check with the actual oil or chemicals
used. In particular, be aware that solvents
such as freon, chlorine, toluene, etc.,
cannot be used.
■ Operation environment
• Although continuous operation of the
switch is possible within the range of
ambient temperature (humidity), as the
humidity range differs depending on the
ambient temperature, the humidity range
indicated below should be used.
Continuous use near the limit of the
range should be avoided.
This temperature-humidity range does
not guarantee permanent performance.
■ Others
• Do not handle the switch in a way that
may cause damage to the sealing rubber
cap.
• Please remember that this switch
cannot be used under water. Also,
pleased be warned that switching and
sudden temperature changes with the
presence of water droplets can cause
seepage into the unit.
• Keep away from environments where
silicon based adhesives, oil or grease are
present as faulty contacts may result
from silicon oxide. Do not use in areas
where flammable or explosive gases from
gasoline and thinner, etc., may be
present.
• When using the lever type, please be
careful not to apply unreasonable load
from the reverse or lateral directions of
operation.
• Do not exceed the total travel position
(TTP) and press the actuator. This could
cause operation failure.
Also, when switching at high speed or
under shock even within the operation
limit, the working life may decrease.
Therefore, please be sure to verify the
quality under actual conditions of use.
• Please make considerations so that the
switch does not become the stopper for
the moving part.
• Do not use the switch which was
dropped by mistakes when handling. If it
is used, abnormal operation
characteristics and sealing performance
may occur.
• In case of applying coating to movable
parts (actuator, plunger, etc.), the quality
of the product is not guaranteed because
it may cause a product failure.
• In case of cleaning a switch, the quality
of the product is not guaranteed because
it may cause a product failure.
• Do not apply ultrasonic vibrations and
high frequency vibration to a switch
because it may have an impact on the
characteristics of the switch.
• Please do not constantly apply a tensile
load to wire leads when fixing them.

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.

This type of construction prevents dust that is large enough to
have an effect on operation from getting inside the unit. This
construction is stipulated by protective classes against solid
matter in the IEC standards (IEC60529).
The talcum powder used shall be able to pass through a square-
meshed sieve the nominal wire diameter of 7 μm. The amount of
talcum powder to be used is 2 kg per cubic metre of the test
chamber volume. The duration of the test is 8 hours.
No damage observed after the test.
■ Immersion-protected type
This type of construction prevents any harmful effects even after
the device is left underwater at a depth of 1 m for 30 minutes.
This construction is stipulated by protective classes against
water in the IEC standards (IEC60529).
■ IEC’s IP Codes
The IEC (International Electrotechnical Commission) has
defined the IP characteristic code that represents the levels of
protection described in IEC standard (IEC60529).
The two numbers that follow the IP code (the characteristics
numbers) indicate the suitability of this protection for all
environmental conditions.
• Level of protection indicated by the 1st Characteristics number
• Level of protection indicated by the 2nd Characteristics number
Note: Details of test conditions are the same as NECA C 0920. Please refer to them.
