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?

In the choice of thin film panel materials, the material physical chemistry performance index is good, its ink is also more extensive, is the thin film switch panel commonly used materials. Prestressed concrete materials differ from sand surfaces and smooth surfaces. The reason for choosing the sand surface material is that the use of the thin film switch is mostly electronic, and the panel as the control system does not want to be disturbed by the light. The sand surface only has diffuse reflection and will not produce bright reflection, at the same time, due to the disorder of the sand surface, it has the function of hiding scratches, on the contrary, the smooth surface material does not have the above characteristics. But as a smooth material, once printed on the back,

The performance of the FPC film key switch is directly related to the normal use of the film key switch. When the film key switch is made into a “Switch”, the connecting wires of the function keys are connected together in advance. Unlike discrete switch elements, each switch pin needs to be connected with a welding wire. Therefore, the thin film switch circuit can avoid welding error, save welding time, and facilitate assembly and connection. This is also the convenience and reliability of the membrane key switch. Since the connection of the membrane switch is prefabricated, the design of the Membrane Switch Circuit shall be submitted to the manufacturer as a process document. Thin-film key switch circuit design can be divided into two. One is the ordinary wire method

How to prevent the windows of the membrane switch from being scratched, the connection of the membrane switch to the display window, and the user’s requirements for the transparency of the windows are very strict and no defects are allowed, in particular, users sometimes use the quality of the glass to check the display window of the membrane switch. Remember someone said that the user is always right, how do we control the window membrane switch? First of all, we should have a high degree of quality awareness, strict control of all production links. The window and the key of the membrane switch are a whole, the key production process is complex, the flow is many, every production link of the membrane switch must consider to protect the window from scratch. Control raw materials, transparency and scratch test levels for purchased raw materials.
