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 different.
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 not endless.
