translucent black glass or PET Capacitive Membrane Switches, capacitive touch membrane keypad

LUPHITOUCH is a professional designer and manufacturer in membrane switch and capacitive user interface membrane keypads technology in China mainland. LUPHI TECH is an ISO9001, ISO13485 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. The overlay material can be thick glass, PMMA, Polycarbonate panel etc. It no longer limited to very thin film material. In addition, for the capacitive touch keypad no longer need 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.

> Key Benefits of Capacitive Switches:

1) Waterproof and easy clean;

2) Fingers light touch and non-conductive gloves touch;

3) Can be backlighting

4) High Durability;

5) Diverse front overlay selection;

6) Friendly interface;

7) Single key or multi-keys or slider;

8) Low current needs;
