We have heard of the Membrane Switch in our life. It is actually a kind of Switch Button . Now the technology is developed, and the switch has been designed into a new look, so it is called a membrane switch, then you all know what the principle of it, as well as membrane switch is what constitutes,the next introduce membrane switch membrane switch and what are the principles of what constitutes, hope your reference.

1. What are the principles of the membrane switch?

(1)For the sake of everyone, the membrane switch is a multi-layer (planar) type (non-locking) button switch composed of a layer of insulating material with certain elasticity, but the integrated circuit. buttons, indicating components, instrument panels, etc. The function is one. The action of the membrane switch is only achieved by the elastic movement of the elastic membrane in a vertical direction. Although the elastic membrane undergoes a million peristaltic movements, the amplitude of the elastic membrane is small.

(2)Next, it is only 0.1-0.3MM, but with the rationality of material selection, the film material can withstand more than one million times of life without deformation, which determines the durability of the membrane switch.

(3) What's more, the membrane switch has beautiful appearance, long service life, simple structure, convenient installation, good hand feeling, and small footprint. It is widely used in all walks of life, from home appliances to high-tech products. Slowly replaced some of the tact switches market, occupying a huge share and advantage in the market.

2. What constitutes a membrane switch?

(1) For everyone to talk about the panel, the panel is the "coat" of the entire membrane switch, based on the appropriate arrangement of the buttons, but through the different colors, patterns, button shapes, and the necessary for the entire membrane switch Decorative effect. The most important function of the panel layer is to play the role of logo and button. The reason why the material must be selected is high transparency, high ink adhesion, high elasticity and anti-folding.

(2) Next, the circuit and the lower circuit: the upper and lower circuits are the electrical components of the membrane switch. This is also the [off" and [key" of the switch, but its performance directly affects the performance of the switchgear. It is formed by printing a layer of conductive material on the film. The upper and lower circuits are responsible for the two electric shock characters necessary for the switch to close, and the thickness is generally within the range of 0.05--0.175 MM, and the most common is 0.125 MM PET.
