The main structure of the film panel is generally composed of buttons and films. The thickness of the membrane switch is generally controlled at about 0.15mm. If it is too thin, there is no resilience, and the use of the switch is not so sensitive. In the case of the Queen Mother, pressing it will be very laborious and it is a bad product.
When the shape of the designed button is relatively large, it is better to select a film with a thickness of 0.18 mm. The thickness of the film is moderate, has a good rebound effect, can be used frequently, and is not easily damaged. If the thickness of the selected film is not enough, it is easy to penetrate. Make the membrane switch use insensitive.
Mechanical membrane switch
Making a flat-panel switch tends to choose a slightly higher thickness when selecting a film to ensure long-term use of the product. Another type of panel used in circuit contact types requires a slightly thinner one, and a thinner film is selected only when the diameter of the bubble is compared.
The overall structure of the membrane button is very simple. When you get a film panel, you can see the circuit and circuit board of the panel. You only need to take the button cover off.
The advantages of the button of the film panel are very many. His working principle is superior to other different types of buttons. It is soldered with a large number of conductive metal points on the surface of a conductive film. Each button can be connected to the same membrane switch. The function of the button of the film panel is different, and the control effect can be realized. The film panel has a barrier layer, and its function is to make a button and a panel react when no one presses, and turn on the circuit when pressed. Complete the instructions.
