What are the applications of membrane switch in mobile phones and electrical appliances?

A lot of people don't know what a membrane switch is, or if they do know something, they think it's rare in everyday life. In fact, the use of membrane keypad has been closely related to our daily life, membrane keypad has become one of the indispensable applications of smart phones. In order to facilitate your understanding and understanding of the membrane switch, we will take you to understand the smart phone today, because it is very common and very common. Smart phones do not have concave buttons, followed by touch buttons, which belong to the category of membrane keypades.

The membrane keypad should be used in most household appliances because of its micro switch characteristics, small size and light weight. We come into contact with many applications, such as TV buttons, DVD buttons, computer buttons, drive buttons, keyboard buttons, display buttons, lighting buttons, etc.

Generally speaking, the application range of the membrane keypad is very wide, not only can meet the requirements of most membrane keypad panels, but also the high transmittance of the smooth PC can meet the requirements of the liquid crystal display window. Its hardness and thermoplastic strength and toughness Z large, low water absorption, wear resistance, friction resistance, high dimensional stability. Tensile strength is also very good, much higher than PC, PVC. The reason for the low price is that the surface is not easy to process into matte, so textured PET is expensive and is an ideal material for making membrane keypading circuits.

In the electronic circuit, the lockless key switch is widely used. Because it doesn't have to go through a lot of electricity. Therefore, its shape and size are usually relatively small, often referred to as touch buttons or microswitches. The mouse button and the phone keyboard are typical examples of the absence of a lock button. Modern electronic devices and tools of human-computer interaction function, human-computer interaction device touch key is a major component of the pleasant system can be driven by user information touch touch, including the contact state of the system time touch, according to the number of times, the length of time and touch which key to decide how to make the appropriate response.

In the development of human-machine interfaces, a technology called film buttons has replaced touch buttons in many cases. According to the needs of the user, the film key can be embedded in the film panel composed of multi-layer films, and the metal wire is generated by printing method. The metal contact is connected with the external connection terminal through the FPC connection belt. Thin film keys have small touch and can achieve multiple keys at the same time. At the same time, the mechanical design of the board is simplified. In addition, it also has a certain waterproof performance, so it is welcomed by many users. However, because the film buckle needs to be customized, the production process is complicated and the cost is high. At the same time, its mechanical contact life limit and other factors, so that its application is also limited.

The company has excellent equipment, complete production process manufacturing platform and a strong professional technical team. membrane keypad products are widely used in communication, paper machine membrane keypad, industrial control, CNC machinery, injection machinery, embroidery machine membrane keypad, sewing machine membrane keypad equipment, spark machine, frequency converter, household appliances, children's toys, instruments, medical equipment, video games, military products and so on.
