Common Precautions for DIP Switch

DIP Switch
Safety Precautions
Precautions
■Precautions for Safe Use
● Soldering
Use the DIP Switch within the rated voltage and current ranges,
otherwise the DIP Switch may have a shortened durability, radiate
heat, or burn out. This particularly applies to the instantaneous
voltages and currents when switching.
Observe the following conditions when soldering the DIP Switch.
■Correct Use
● 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,
soldering, washing or drying Switches. 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
recommended.
Holes on the PCB should be at least 0.9 mm in diameter for
automatic 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
Surface-mounting types)
Align the terminals so they slide in simultaneously when the
Switch is inserted into socket holes or into mounting holes predrilled 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.

1. General Precautions for Soldering
Make sure that the actuator of slide-type DIP Switches is set fully
to either ON or OFF. (For A6TN, A6SN, 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.
2. Automatic Soldering Bath (Flow Soldering)
Soldering temperature: 260°C max.
Soldering time: 5 s max. for a 1.6-mm thick, single-side PCB
for A6TN
Soldering temperature: 265°C
Soldering time: 8 s max. for a 1.6-mm thickness single-side PCB
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 soldering conditions and the temperature around the Switch
may vary with the type of reflow bath. Check the temperature
profile and confirm soldering conditions as well as the amount of
heat applied to the Switch prior to soldering.
4. Manual Soldering (Except Surface mounting type
*See Note)
Soldering temperature: 350°C at the tip of the soldering iron.
Soldering time: 3 s max. (For A6TN and A6SN Soldering
temperature: 400°C Soldering time: 4 s max.) for a 1.6-mm thick,
single-side PCB
Do not solder the Switch more than twice including any
rectification soldering. An interval of five minutes is required
between the first and second soldering. (For A6TN and A6SN,
soldering is available only once.)
Note: Even though, manual soldering is available for A6SN.
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.

2. Washing Procedure
Ultrasonic cleaning is not available for slide-type DIP Switches
with seal tape. These models may be wiped or dipped into
washing agents for one minute maximum.
Slide-type DIP Switches with seal tape can be washed as long as
the seal tape is not removed or pasted before washing. Noncompliance here will cause the quality of the seal to decline.
Washing equipment incorporating more than one washing bath
can be used to clean washable models, provided that the
washable models are cleaned for one minute maximum per bath
and the total cleaning time does not exceed three minutes.
3. Washing Agents
Apply alcohol-based solvents to clean washable models. Do not
apply water or any other agents to clean any washable models,
as such agents may degrade the materials or performance of the
Switch.
4. Washing Precautions
Do not impose any external force on washable models while washing.
Do not clean washable models immediately after soldering. The
cleaning agent may be absorbed into the incomplete seal through
respiration as the Switch cools. Wait for at least three minutes
after soldering before cleaning.
Do not use washable Switches submerged in water or in locations
exposed to water.

Safety Precautions
● Handling
1. Slide-type DIP Switch operation
Although raised-type and piano-type actuators can be operated
by fingertip, do not push too hard or too fast because this will
deform or damage the actuator.
When setting or operating the A6H, use narrow-headed tweezers
or similar implement (without a sharp end), to enable smooth,
horizontal operation. Pushing the actuator at an angle, or
applying excessive load from above may damage or deform the
actuator and thereby prevent operation.
Do not apply excessive operating force to the Switch. Otherwise
the Switch may be damaged or deformed, and the switch
mechanism may malfunction as a result. Apply an operating force
not exceeding 9.8 N {1,000 gf}. (Actuators may break if they are
operated from the tip. Operate the actuators one at a time so that
pressure is not concentrated at the tip. (Use a force of 7.8 N
{795 gf} or less for the A6TR and A6SR.))
Apply operating force within the range of rated values for A6HR,
small sizes piano type. Apply the operating load from the side of
the actuator. Do not apply a load from an angle or from above the
actuator. Doing so may deform the Switch contact.
2. Rotary DIP Switch Operation
Set rotary-type DIP Switches with a flat-blade screwdriver that fits
into the screwdriver groove. Using a screwdriver of inappropriate
dimensions, or using a tool other than a flat-blade screwdriver
may cause damage to the groove that may make the Switch
impossible to operate.
Insert the flat-blade screwdriver vertically to operate the Switch.
The Switch may be damaged if the screwdriver is inserted at an
angle.
Do not use excessive force to operate the Switch, or it may
damage or deform the Switch.

Correct
3. Setting
Set slide-type DIP Switches with a tiny, rounded object, such as
the tip of a ball-point pen or a small screwdriver. Do not set the
DIP Switch using tweezers or any other sharp object that may
damage it. Do not set the DIP Switch using the point of a
mechanical pencil, or lead powder or fragments may fall into the
Switch and internal circuit board, causing the DIP Switch to
malfunction and reducing the dielectric strength of the circuit
board.
Set the Switch to the correct position before use. An incorrectly
aligned position may result in incorrect signals.
