LUPHITOUCH is a professional designer and manufacturer of captive
membrane switches and user interface membrane keypads technology in
China mainland. LUPHITOUCH is also an ISO9001, ISO13485, ISO14001,
and OHSAS18001, certified manufacturer. Our capacitive touch
membrane keypad consists of one or more capacitive touch buttons.
We print the capacitive touch buttons/sensors on PET circuit with
the transparent conductive ink. We also use ITO etching technology
to make the capacitive touch buttons/sensors.
Through the customized IC chip to control the touch function
wanted. Except for the capacitive touch keypads we also manufacture
the capacitive touch sensor circuits.
By capacitive touch technology, the overlay materials can be very
diverse and not only limited to PET or PC super thin films. For the
normal membrane keypads, the function triggered by the mechanical
buttons(metal domes or Polydome) and also the common membrane
keypads only can use PET, PC film for the graphic overlay.
Use a heavy force to press the buttons to make the conductive pads
of the Polydome ormetal domes connected to the conductive pads on
circuit layer, then become a loop circuit and occur the function.
But for the capacitive touch membrane keypads or circuits, it is
We use a variety of overlay materials such as thick glass, PMMA,
Polycarbonate panels, etc. The material choice is no longer limited
to only a very thin film material, on the contrary, the options are
In addition, the capacitive touch keypad no longer needs heavy
force to press buttons, you only need tiny touch the buttons, then
the sensor pad can connect the circuit loop and occur the function.
LUPHITouch: The Industry Leader
Since LUPHITOUCH closely follows up the industry trend, therefore,
we are always steps forefront of domestic peers. We have also
successfully developed our own capacitive membrane switches and
inductive circuit foils.
Capacitive membrane switches consist of the top cover and the
bellow sensor circuit. So, the top cover of our capacitive membrane
switches can be from 0.15mm to 5.0mm thick PMMA, PC, glass, or
other plates, which can cover nearly all different end market
Likewise, the sensors on the inductive circuit can be printed on
the PET film or etched on the ITO film. The different likes bellow:
|Item||Printed Sensor||ITO Etched Sensor|
|Light Transparency||Low (70~85%)||High (90~99%)|
Key Benefits of Capacitive Switches:
- Waterproof and easy to clean
- Fingers light touch and non-conductive gloves touch
- Can be backlighting
- High Durability
- Diverse front overlay selection
- Friendly interface
- Single key or multi-keys or slider
- Low current needs
Applications for Capacitive Membrane Switches/Capacitive Touch
- Medical equipment, devices
- Healthcare devices
- Dirty, oil contamination, wet environment
- Household appliances
- Industrial Control
- Aviation and Boat
