Most of the membrane switches are made of single-sided hairy polycarbonate film, which is printed on the smooth surface of the polycarbonate film by means of screen printing. They play a nominal, decorative and prompt role on the panel. Therefore, membrane switch manufacturers must take different technological measures in screen production.

Film switch screen printing is similar to general plastic film screen printing. Before printing, the substrate film should be preprinted. The pictures and texts shall be printed on the back of the panel, that is, on the non-touch surface of the panel, to ensure that the pictures and texts on the electronic membrane switch are clear and free from wear. The text on the panel plays an important role in indicating functions, transmitting instructions and stating contents. It requires the smoothness of screen printing edges and the integrity of strokes. Therefore, the film layer of the text screen should have a certain thickness to ensure that the screen printing handwriting button layer is thick, so that the handwriting is clear, durable, eye-catching and beautiful. Photosensitive film with different thickness is suitable for different occasions.
For example, thin film should be used for fine characters to improve the clarity of handwriting; Light color text or pictures and texts printed directly in three primary colors require that the film should be thick, so as to make the color more pure. In addition, a transparent window is usually set on the panel layer of the membrane switch. Its function is to provide the establishment of a certain switch function or reflect the working state of the whole machine, so that the operator or other personnel can manage the whole machine.
