How The Membrane Switch Panel Works

The main structure of the film switch panel is generally composed of buttons and films, the thickness of the film switch will generally be controlled at about 0.15mm, if too thin, there is no rebound force, the use of the switch is not so sensitive, if too later, press will be very laborious, are not good products. The flat-panel switch will tend to select a slightly higher thickness when selecting a film to ensure long-term multiple use of the product.

Another application in the circuit contact type panel requires the use of a slightly thinner, only when the diameter of the bubble is compared, the use of a thinner film is selected.

The overall structure of the film button is designed to be very simple, and when you get a film panel, you can see the circuit and circuit board of the panel by simply taking the key cover off. When the shape of the design button head is relatively large, it is best to choose 0.18 mm thickness of the film, this thickness of the film thickness is moderate, with a good rebound effect, can be used frequently, not easy to damage. If the film thickness selected is not enough, it is easy to penetrate.

Makes the film switch insensitive. The keys of the thin-film switch panel have many advantages, he works in contrast to other different types of keys, it is welded on top of a conductive film a lot of conductive metal dots, each key can be connected to the same film switch film panel button is how to work the line, can achieve different control effects, The film panel has a barrier layer, its role is to do a key and panel reaction when no one presses, press on the circuit.
