AV3/AVM3/AVT3/AVL3 (FS/FS-T) Subminiature Switches
CAUTIONS FOR USE (Common for FS type and FS-T type)
■ Regarding fastening of switch body
1) To secure the switch, please use an M2.3 small screw on a
flat surface and tighten using a maximum torque of 0.29 N·m.
It is recommended that spring washers be used with the screws
and adhesive be applied to lock the screws to prevent loosening
of the screws.
2) When the operation object is in the free position, force should
not be applied directly to the actuator or pin plunger. Also force
should be applied to the pin plunger from vertical direction to the
switch.
3) In setting the movement after operation, the Overtravel OT
should be set not less than 70% as a standard.
Setting the movement at less than 70% of OT may cause
troubles such as mis-contact and welding due to small contact
force of the switch.

area
■ Soldering operation
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.
■ Environment
Locations where corrosive gases having a bad influence on
contacts are present, and locations where there is an excessive
amount of siliceous or other abrasive dust should be avoided.
■ Regarding connector connections (.110 quick connect
terminals)
For making connections, a dedicated receptacle for .110 quick
connect terminals should be used, and the terminals should be
inserted parallel to the receptacle. Consideration should be
given to mounting so that no tensile load is applied to the lead
wires.
■ In making the switch selection
Consideration should be given to provide for no interference up
to +20% variation of the standard characteristics values.

In addition, even if FS type switch actuator is pushed to full limit
of operating position, it does not affect product life. However,
heavy impact and excessive loading should not be applied.

(Both AV3/AVM3 subminiature switches and ABS turquoise switches)
The .110 Quick-connect terminal type of S type turquoise switches and FS type subminiature switches fit direct contact 3P connectors
(Nippon Tanshi Co., Ltd.)
■ Reverse insertion prevention
As shown in the diagram, the protrusion on the 3P connector
can only be inserted on the corresponding side of the mounting
frame. That is, using the plunger as a reference, the
subminiature switches can only be inserted in the direction
shown in the diagram: it is not possible to mount it the wrong
way round.

Technical Terminology & Cautions for Use
Technical Terminology & Cautions for Use
(Detection Switches)
TECHNICAL TERMINOLOGY
■ Detection Switches
A compact switch equipped with an enclosed micro-gap snapaction 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
A part of the switch that transmits the received external force to
an internal spring mechanism to move the movable contact so
that the switch can be opened and closed
■ Actuator stopper
A part of the switch to limit the actuator movement in the switch
operation direction
■ 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.).
■ 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.)
■ 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.)

■ Contact form
This refers to the
components
determining the type
of application which
make up the electrical
input/output circuits in
the contact.
SPDT
SPST-NC

■ Insulation resistance
Resistance between non-continuous terminals, each terminal
and other exposed metal parts and between each terminal and
ground.
■ 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.
■ 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
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.

reason, use the
switch while giving
due consideration to
this. This also causes
the snap action
switch to be sensitive
to vibration or shock.
Operating force
■ 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.

■ 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.
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.

Use of a driving mechanism which will cause physical impact to
the actuator should be avoided.

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).

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.
CAUTIONS IN A CIRCUIT

switches are used in an inductive load circuit.

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
Reference values: OP = 8.8±0.8mm
PT = max. 2.8mm
OT = min. 1.2mm
FP
OP
TTP
PT
OT
(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.
■ 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.

Technical Terminology & Cautions for Use
■ 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.

■ 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, opencircuiting 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.
+85
+185
(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.
