Membrane switch: What is a membrane switch? Membrane switch is a combination of switch keys, panel function text, Mark, trademark, transparent window and display window, and is a multi-layer overall seal, structure, and with friction-resistant, waterproof, dustproof, against harmful gases, long service life and stable performance and so on. Thin film switches have been widely used in intelligent electronic measuring instruments, medical instruments, computer control, CNC machine tools, electronic scales, post and telecommunications, copiers, refrigerators, microwave ovens, electric fans, washing machines, video Game Console and other industrial and household electrical products. Membrane switch: What are the uses of membrane switchMembrane switch: What are the characteristics of the metal shrapnel type membrane switch? Film Switch: What is the film switch, film switch use, film switch has been widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields. Thin film switch: Thin Film switch is how to do, thin film switch also known as light touch keyboard, the use of plane multi-layer combination of the overall sealing structure. It is a new electronic component which can seal the key switch, the panel, the mark, the symbol display and the lining board together. The utility model has the advantages of good water-proof, dust-proof, oil-proof, erosion-proof by harmful gases, stable and reliable performance, light weight, small volume, long service life, washable panel, no damage to characters, rich and beautiful color, etc. . The membrane switch is mainly composed of the mask layer, the circuit layer and the isolation layer. The line layer is divided into upper line layer and lower line layer. The upper circuit layer and the lower circuit layer are printed on a non-conductive film (PET) with conductive silver or carbon paste and non-conductive insulating ink. Isolation layer is plastic layer, the middle for the different thickness of the material plus double-sided back glue, mainly play up and down the line of isolation and bonding. When the contacts of the upper circuit layer are squeezed, the contacts of the upper and lower circuit layers are connected, and the circuit is opened to form a path, thus playing the role of a switch.
