Touch Switch Module Handling and Usage Precautions
Please follow the appropriate product application notes and operation standards for proper usage, safe handling, and
ideal performance.
【The Glass Touch Switch Panel】
In the case of the Touch Switch panel’s edges are
not smooth, it requires careful handling to avoid
injury.
Be careful to avoid breaking the Touch Switch panel as
the resulting sharp glass particles may cause injury.
Do not intentionally destroy the Touch Switch panel.
Do not use with a sharp object as it will scratch and
damage the panel surface.
To clean the surface of the Touch Switch panel, use a
soft cloth and glass cleaner and do not use organic
solvents, acids, or alkalis.
Touch switch panel surface is made only of glass.
For washing, an acidic or slightly alkaline detergent
for glass can also be used.
【Cable Connection】
Do not unplug the power and/or data cables from
the Touch Switch module during operation, this may
result in permanent damage to the module.
Sending input signals to the Touch Switch module
when it is not powered can cause I/O port damage.
It is recommended to use a 30cm or shorter signal
cable to prevent functional failures.
【Electrostatic Charge】
Touch Switch modules need electrostatic-free
packaging and protection from electrostatic charges
during handling and usage.
【Structure】
It is recommended to use UL-grade materials or
components in conjunction with Touch Switch
modules.
Bending and twisting causes stress and may break
the Touch Switch panel and module. Please
minimize chassis movement to accommodate for
the 0.3mm attachment point gap. Failure to do so
may result in panel damage.
Do not apply force to any FPC or cable running from
the control board to the Touch Switch panel.
【Power】
Apply regulated power to the Touch Switch module
within the specified voltages to protect from failures.
The Touch Switch module needs a specific voltage
to operate properly. Please use a reliable power
cable to avoid a voltage decrease. As a safety
measure, a fuse or another type of over-current
protection is recommended.
-4-
Touch Switch modules may draw in-rush current
exceeding twice the typical current at power-on, so
a power supply with sufficient capacity and a
quick-starting power regulator is recommended.
TKU016CT-A100
【Implementation】
Avoid contact with metal.
If you would like to create a waterproof application,
we recommend that a sturdy and durable sealing
material is used between the panel’s gasket area
and the chassis.
【Storage and Operating Environment】
Please use our Touch Switch modules under the
specified environmental conditions only.
If used in a high temperature environment, there is a
possibility that the Touch Switch panel surface may
be hot.
Salty, sulfuric, and dusty environments may damage
the module even during storage.
There is a risk of burns and other injuries so be
careful when touching the panel.
【Disposal】
Touch Switch uses materials that contain lead (the
RoHS directive exempts these lead compounds for
glass that is used with electronic devices).
When discarding the Touch Switch panel or Touch
Switch module, please adhere to the applicable
laws and regulations.
【Other Precautions】
Although the Touch Switch module is designed to be
tolerant of electrical noise, please place an
emphasis on noise reduction in your circuit design.
Do not reconstruct or repair the Touch Switch
module without our authorization. We cannot assure
the quality or reliability of unauthorized and
reconstructed Touch Switch modules.
We do not authorize the use of any patents that
may be inherent in these specifications.
Whole or partial copying of these specifications is
not permitted without our approval. If necessary,
please ask for our sales consultant for assistance.
This product is not designed for military, aerospace, medical or other life-critical applications.
If you choose to use this product for these applications, please ask us for prior consultation or we cannot accept
responsibility for any problems that may occur.
