The Basic Structure Of The Membrane Switch
2023-04-17
The basic structure of the Membrane Switch, which is an optical collection, a new electromechanical integration of electronic components. This is a fundamental change in the appearance and structure of electronic products. Membrane Switches can easily replace the push-Button buttons of traditional discrete components and perform the tasks of the operating system more reliably. Film Switch is waterproof, dustproof, oil and harmful gas resistance. It has the advantages of stable and reliable performance, light weight, small size, long service life, convenient assembly and connection. Washable panel will not damage the character, rich color, beautiful and generous. Many friends know little about the basic structure of the membrane switch principle. Generally speaking, the common Membrane Keypad switch is mainly composed of six layers of material. From the surface to the inside, it is the panel, the glue, the circuit, the isolation layer, the circuit and the glue. 
Membrane Keyboard panel is the entire thin-film switch "coated" on top of the correctly aligned keys. Through different colors, patterns and key shapes in the whole film switch plays a necessary decorative role. The main function of the panel layer is to identify, play a key role. So the selected materials need to have high transparency, high ink adhesion, high elasticity, folding resistance and other characteristics. The upper circuit and the lower circuit, the upper and lower circuit are the electrical components of the film switch. It is also the switch "off" and "key". Their performance directly affects the performance of the switch. The switch is mainly formed by printing a layer of conductive material on the film. The two shocks required for the upper and lower circuits to close as switches are usually between 0.05 and 175MM thick, with a common PET of 0.125 mm. Keypad top adhesive, isolation layer and bottom adhesive. These three layers of material are double-sided tape, because of the different positions in the switch structure, so there are different names. The thickness of the three double-sided tape varies according to the number of layers. This mainly depends on the thickness of the switch and the operating force of the key. What is the quality of the keypad switch? It is because of the friction resistance of the membrane switch, waterproof, dustproof, and harmful gases. Long service life, stable performance, so in the intelligent electronic measuring instrument has been widely used. Computer control of medical instruments, CNC machine tools, electronic scales, electronic scales and other industrial and household appliances, post and telecommunications, photocopiers, refrigerators, microwave ovens, electric fans, washing machines, electronic game consoles and so on.
