Polyester Custom Made Button Membrane Switch
Membrane keypads and membrane switches offer designers of electronic equipment a flexible, customizable user interface which is compact, versatile, reliable and assembly friendly.
Construction
Constructed of layers of polyester (PET) film combined with spacers and adhesive, electrically conductive inks are printed onto the film to form a circuit. Total thickness is typically 1-2mm. Depending on the application and environment, graphic overlay materials can be specified to resist harsh environments such as high moisture, high UV and chemicals. Tactile Feedback of switches can be built into the keypads by insertion of stainless steel tactile discs or embossing of the overlays. Permark can supply either Female Clinch or ZIF connectors
