What are the characteristics of the FPC film key switch configuration? The thin film switch panel is formed by pressing the thin film switch sheet and can not discharge the pressure when cutting the hollow line of the adjacent sheet-shaped keys, the surface of the flat key is bonded directly to the bottom of the transparent film by hollow words, numbers or symbols. The utility model relates to a membrane switch panel, in particular to a membrane panel key forming structure, which combines a membrane switch panel with a corresponding control panel, the embossing body arranged on the central convex surface of the bottom surface of the transparent plastic film is opposite to the touch switch arranged on the control panel to form a combination of compressible contact point control, which can save a great deal of manufacturing cost and man-hour cost per assembly. The main features of the key forming structure of the membrane switch panel are as follows: The utility model is characterized in that the sheet key shape with proper pressure and resilience is arranged by a hollow line, do not move the adjacent keys while the hollow wire is being cut and pressed. Each keyboard surface directly hollowed out a number, character or symbol, each keyboard bottom paste a layer of transparent film, sealed with transparent plastic film key, hollow, waterproof, transparent display text, numbers and symbols.What are the advantages of a thin-film key over a traditional silicone key? Compared with the traditional silicon bonding, the thin film bonding has better handle and longer service life, which can indirectly improve the production efficiency of all kinds of switches using conductive film. Thin Film Key light weight, small size, beautiful, touch-type thin film switch long service life. The conductive Zebra Strip is moisture-proof, dustproof, drop-proof, shock-proof and easy to install. Thin-film keyboard features only the panel has been raised, feel raised from the panel, not ideal. The conductive ink is printed directly on a raised area on the back of the panel. The cost of membrane switches is low, and the lifetime of membrane switches is directly affected by the size, shape and height of the impact, ranging from 100,000 to 300,000 times. Storage and use temperature is limited, high temperature easy membrane switch button height low. According to the makers of conductive zebra strips, the metal shrapnel on the thin-film keyboard is located in the conductive portion of the printed circuit board (mostly above the printed circuit board’s gold finger) . Under pressure, the center point of the shrapnel depression, contact circuit board, the formation of a circuit, current through, the whole product can work properly. A metal dome switch is a thin pet board containing a metal warhead (which can be fragmented) that acts as a switch on the PCB or FPC etc. . It is an important tactile switch between the user and the instrument.
