Focus on thin film switches!

A switch is defined in modern terms as the element that controls a circuit switch. In ancient times the definition of a switch was much larger. The word switch can be traced back to the Shang and Zhou dynasties thousands of years ago. From a physical point of view, it can make a certain object through a certain link or fulcrum can play a decisive role in the whole system, just like the water gate is one of the most primitive switches. Now switches can be seen everywhere, all kinds of switches appear in life. Such as light switch, microwave switch, large machine switch and so on. But society keeps evolving, so there are all kinds of switches. Next, let's take a look at the history of the development of membrane switches. Like the toggle switch in the 1950s. Toggle switch is a manual control switch mainly used for AC and DC power supply circuit control. It is characterized by small size and easy operation. It is common in electronic devices. Then came the toggle switch of the same period. The principle of toggle switch is to cut off or close the circuit by toggle the contact of plastic handle. The switch is mainly used in low-voltage circuit, which is characterized by small size, multi-function response speed and strong resistance to electricity, light and magnetic interference. Mainly used in all kinds of instruments and instrumentation equipment. And electronic products such as electric toys, audio equipment and medical equipment Then there is the contemporaneous switch. It is a switch for two or more power supply or load conversion. The switch consists of contact system, positioning system, handle and other components. It is characterized by small installation area, simple structure, compact, safe operation and reliability. Mainly used in circuit control and electrical equipment. Over time, in the late 1970s, thin-film switches were introduced and continue to this day. Membrane switch is also known as light touch keyboard, it is made of FPC, PVC, PET, PC, double-sided glue and other materials, it is made by screen printing technology made of multi-plane combination seal set graphics, keys, punctuation marks, electrical conductivity and electronic switch functions as one of the plastic electronic products, simple and widely used. With the development of electronic technology requires the development of the fifth generation of products. Its structure is panel layer, cushion rubber layer and control circuit of the upper and lower layer and the clamp layer. Its function is the same as the fourth generation of product key switch, diaphragm switch key panel has different types, can make different industries have their own exclusive products.
