YouMi Capacitive Membrane Switches AND Membrane Keypads

YouMi Capacitive Membrane Switches  AND Membrane Keypads YouMi is a professional designer and manufacturer in membrane switch and capacitive user interface membrane keypads technology in China mainland. YouMi is an ISO9001 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.
