Precautions
Circuit Design
Use the DIP Switch within the rated voltage and current ranges,
otherwise the DIP Switch may have a shortened life expectancy,
radiate
heat, or burn out.
Mounting
Do not operate the DIP Switch while mounting, soldering, or wash -
ing
the DIP Switch, otherwise the DIP Switch may deform due the
heat of the solder, the DIP Switch may malfunction due to the pe-
netration of the washing agent, or the machine incorporating the
DIP
Switch may operate or be set incorrectly .
An automatic insertion machine incorporating a body stopper is
available
for mounting the DIP Switch. When using an automatic in -
sertion
machine incorporating a half-lead stopper to mount the DIP
Switch, make sure that the automatic insertion machine will not de -
form
the terminals of the DIP Switch, otherwise the improper inser -
tion
of the DIP Switch may result.

Soldering
Observe the following conditions when soldering the DIP Switch.
Automatic Soldering Bath
Soldering temperature: 260°C max.
Soldering time: 5 s max. for a 1.6-mm thick,
single-side PCB
Reflow Soldering

max.
Manual Soldering
Soldering temperature: 350° C at the tip of the soldering iron.
Soldering time: 3 s max. for a 1.6-mm thick,
single-side PCB
Set the pins of the DIP Switch to OFF before soldering the DIP
Switch.
Before
soldering the DIP Switch on a PCB, make sure that there is
no unnecessary space between the DIP Switch and PCB.
Before soldering the DIP Switch on a multilayer PCB, make sure
that
the DIP Switch will not be deformed by the soldering heat on the
pattern or land of the multilayer PCB.
Do not solder the DIP Switch more than twice including rectification
soldering. An interval of five minutes is required between the first
and
second solderings.
Make sure that there is no flux rise on the surface of the PCB.

Washing
Washable A6T (with seal tape),
A6S (with seal tape)
Not washable A6T (standard/raised actuator),
A6S (standard/raised actuator)
Ultrasonic cleaning is unavailable to any A6T or A6S-series DIP
Switch
with a seal tape. It is possible to wipe or dip these models into
washing agents for one minute maximum.
Apply fluorocarbon or alcoholic solvents to clean washable models.
Do not apply any other solvents or water to clean any washable
model
because they may deteriorate the materials or performance
of the model.
Washing equipment incorporating more than one washing bath can
be used to clean washable models provided that the washable mod -
els are cleaned for one minute maximum per bath and the total
cleaning
time does not exceed three minutes.
Do not impose any external force on washable models while wash -
ing.
Do
not clean washable models immediately after soldering. W ait for
at least three minutes to clean washable models after soldering.
The A6T or A6S-series DIP Switch with a seal tape can be washed
provided that the seal tape is not removed or pasted before washing
the DIP Switch.

Handling
Do not apply excessive operating force to the DIP Switch, otherwise
the DIP Switch may be damaged or deformed, thus causing the
switch mechanism to malfunction as a result. Apply an operating
force
not exceeding 200% of the maximum rated operating force to
the DIP Switch.
Set
the DIP Switch incorporating slide pins with a tiny , rounded ob -
ject,
such as the tip of a ball-point pen or small screwdriver . Do not
set the DIP Switch using tweezers or any other sharp object, which
may damage the DIP Switch. Do not set the DIP Switch using the
point of a mechanical pencil, otherwise lead powder or fragments
may
fall into the DIP Switch and internal circuit board, causing the
DIP Switch to malfunction and reducing the dielectric strength of the
circuit board.
