PCB membrane switch panel typically comprise a front panel layer, surface adhesive layer, upper and lower control circuit layers, laminating layer, and rear adhesive layer. The front panel layer employs colourless, translucent sheets such as PET or PC, onto which patterns and text are screen-printed to serve as identification and keypads; The front adhesive layer bonds the front panel layer to the circuit layers, achieving sealing and connection. The upper and lower control circuit layers utilise polyester film as a substrate, screen-printed with conductive silver paste and conductive carbon paste to impart electrical conductivity. The laminating layer is positioned between the upper and lower circuit layers, serving a sealing and bonding function. The rear adhesive layer facilitates the attachment of the membrane switch to the device.
PCB membrane switch panel type characteristics:
By structure, they can be categorised into flat non-tactile types, film convex tactile types, convex bezel non-tactile types, convex bezel tactile types, embossed panel tactile types, metal spring sheet types, illuminated types, foldable types, and inner/outer frame waterproof types. Each type exhibits distinct characteristics in tactile feedback, service life, and appearance.
PCB membrane switch panel application
