AV4 (FU) Switches
GUIDELINES FOR USAGE
Fastening of the switch body
Cleaning
1) In fastening the switch body, use the M1.4 screw (3 types
... screw head diameter from 2.4 dia. to 2.6 dia.), with
tightening torque of not more than 0.098 N·m.
2) In setting the movement after operation, the over-travel
should be set within the range of the minimum OT value.
Please set up so that a operation object does not apply
force to the switch body.
As AV4 (FU) switch is not completely sealed construction,
avoid cleaning.
Environment
hen switching low-level circuits (max. 100 mA), Au
W
plated contact types are recommended.
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.
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.
Soldering
1) Manual soldering should be accomplished within 5 seconds
with max. 320°C iron. Care should be taken not to apply
force to the terminals during soldering.
2) Terminal portion must not be moved within 1 minute after
soldering. Also no tensile strength of lead wires should be
applied to the terminals.
3) When using the angle terminal type, insert an insulation
separator between the switch body and the P/C board
(Insulation separator 0.2 to 0.4 mm thick) to prevent the
soldering flux from flowing under the P/C board.
Please refer to "the latest product specifications"
when designing your product.

Technical Terminology & Cautions for Use (Detection 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 (N.C.) circuit, the driving mechanism
should be set so that the actuator is normally in the free position.
For a normally open (N.O.) 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.
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.
Contact force
Operating force
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.
Driving Mechanism
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 lowcapacity 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 thebeginning 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 N.C.
terminals is measured in the free position, while contact resistance
across COM and N.O. 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
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.
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.
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.
<Examples>
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.
The following describes the case where the strictest tolerance
conditions are adopted.
Example: Hinge lever type FS switch
Reference values: OP = 8.8±0.8 mm
PT = Max. 2.8 mm
OT = Min. 1.2 mm

2) Environments where gasoline, thinner or other flammable, explosive

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.
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.
Storage precautions
To prevent discoloration due to sulfurization of the terminals (silverplated), store the switches in a polyethylene bag or other suitable
airtight container.

Technical Terminology & Cautions for Use (Detection Switches)
sage, storage, and transport conditions (except
U
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.

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.

(The allowable temperature depends on the switch.)
ondensation will occur inside the switch if there is a sudden
C
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.
