Precautions
Safety Precautions
■
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. This particularly applies to the instanta-
neous voltages and currents when switching.
■
Circuit Design
Although the minimum current is 10 µ A (3.5 VDC), contact reli-
ability may need to be improved in some cases. This is particu-
larly true when switching causes an increase in instantaneous
current, such as in C-MOS IC applications. Do not let the peak
current exceed the rated value here or any other time.
Only BCD/hexadecimal 1-2-4-8 code is available for A6C/A6CV/
A6R/A6RV models. If BCD/hexadecimal 1-2-4-8 complement
code is required, make the appropriate provisions in the circuit.
Mounting
Normally the default striker setting is OFF for slide-type DIP
Switches and the default rotor setting is 0 for Rotary DIP
Switches. Do not change these settings when mounting, solder-
ing, washing or drying Switches. In rare cases, the striker may be
deformed by heat generated during soldering.
1. Automatic Insertion Machine
Use a body stopper system for the chute stopper of automatic
insertion machines. When mounting Switches using an insertion
machine incorporating a half-lead stopper, make sure the
machine will not deform the terminals of the Switch, or improper
insertion may result. Check actual mounting conditions prior to
using a half-lead stopper system.
A printed circuit board that is 1.2 to 1.6 mm thick is recom-
mended.
Holes on the PCB should be at least 0.9 mm in diameter for auto-
matic insertion.
2. Manual or IC Socket Insertion
Commercially available insertion tools are recommended for
mounting ICs on PCBs.
Terminal pitch, dimensions and other features are identical to that
of standard ICs for IC socket compatibility (except for the A6S-H
and A6H).
Align the terminals so they slide in simultaneously when the
Switch is inserted into socket holes or into mounting holes pre-
drilled at the specified dimensions. Apply downward force on the
Switch until the terminals are properly seated on the PCB.
Do not try to remove a Switch by inserting a screwdriver between
it and the PCB, and then twisting the screwdriver to peel the
Switch off. Use a commercially available inserter/remover to
remove the Switch.
Soldering
Observe the following conditions when soldering the DIP Switch.
1. General Precautions for Soldering
Make sure that the striker of slide-type DIP Switches is set fully to
either ON or OFF. (For A6E and A6ER models, however, set the
Switch to OFF before soldering.) Make sure that Rotary DIP
Switches are correctly set to 0. Misalignment may result in
reduced sensitivity due to the soldering heat.
Before soldering the Switch on a PCB, make sure there is no
unnecessary space between the Switch and the PCB.
Before soldering the Switch on a multilayer PCB, conduct a test to
make sure the Switch will not be deformed by soldering heat on
the pattern or land of the multilayer PCB.
Cautions
Correct Use
2. Automatic Soldering Bath (Except A6S-H/A6H)
Soldering temperature: 260 ° C max.
Soldering time: 5 s max. for a 1.6-mm thick, single-side PCB
Do not use an automatic soldering bath or manual soldering for
A6S-H or A6H models.
Confirm in advance that flux will not bubble up onto the side of the
PCB to which the Switch is mounted. Depending on the type of
Switch, the flux may have an adverse effect if it enters the Switch.
The A6S-H and A6H are designed specifically for reflow solder-
ing. Do not use an automatic soldering bath or manual soldering
for these models.
3. Reflow Soldering
Observe the following conditions for reflow soldering the A6S-H
and A6H models. (Measurement location: Top of Switch)
Do not use reflow soldering for any models other than the A6S-H
and A6H. Otherwise the plastic case may melt or deform.
The soldering conditions and the temperature around the Switch
may vary with the type of reflow bath. Check the temperature pro-
file and confirm soldering conditions as well as the amount of
heat applied to the Switch prior to soldering.
4. Manual Soldering (Except A6S-H/A6H)
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
Do not solder the Switch more than twice including any rectifica-
tion soldering. An interval of five minutes is required between the
first and second soldering.
5. Using Flux
Making mistakes in the type of flux or in the amount or method in
which it is applied can cause flux to enter the interior of the
Switch, with adverse effects on Switch performance. Assess the
proper flux, conditions, and methods prior to using it.
