Working Principle of Membrane Switch
Membrane switch is a type of switch commonly used in electronic devices. It consists of a very thin elastic film, usually made of materials such as polyester or polyamide. Membrane switches are usually used in devices such as touch screens, keyboards, remote controls, etc., so that users can complete the switch operation by touching the film lightly. The working principle of membrane switch is based on the elastic deformation of the film. Metal contacts are arranged on the film. When the user touches or applies pressure on the film, the film will deform slightly, causing the contacts of the metal contacts to make a connection or disconnection action.
The working principle of membrane switch can be divided into the following steps:
1. Contact: When the user touches the membrane switch, the finger pressure will be applied to the film, causing the film to sag inward, so that the adjacent metal contacts contact each other.
2. Conductivity: When the metal contacts are in contact, a path is formed, and the current can flow through the metal contacts, thereby realizing the conduction of the circuit.
3. Disconnection: When the user stops applying pressure, the film returns to the initial equilibrium state, the metal contacts return to the separated state, and the current cannot pass through the metal contacts, realizing the disconnection of the circuit..
The advantages of membrane switches include simple structure, small size, light weight and long service life. At the same time, because the working principle is based on light touch, it can also realize functions such as touch sensing and sensitivity adjustment. Through the optimized design of membrane materials and metal contact structures, membrane switches can achieve wear resistance, waterproof and corrosion resistance, so as to better adapt to various application scenarios.
What is a membrane switch?
Membrane switch, also known as touch keyboard, is a multi-plane combination sealed plastic electronic product made of soft materials such as PC, PVC, PET, FPC and double-sided adhesive using screen printing technology, integrating graphics, buttons, mark symbol display, conductivity and electronic switch functions.
The main features of membrane switches are:
1. Small and light: The weight of a general membrane switch ranges from a few grams to dozens of grams, which is very easy to carry and disassemble;
2. Beautiful: Modern perfect silk screen technology, coupled with perfect design, can produce any pattern you need;
3. Sealing: Using unique technology, the membrane switch can be waterproof, oil-proof, anti-pollution, anti-static interference and other functions;
4. Excellent conductivity: The circuit of the switch can be printed with carbon paste, silver paste, copper platinum, etc., and the conductive layer can be folded at will; and the resistance can be controlled
at any resistance you want, and with unique technology, the membrane switch made can even withstand high-voltage electric shocks of more than 100,000 volts without damaging its function;
5. Low cost: Some membrane switches are even sold for only a few cents. Compared with an electronic component product with such a multi-function, its price advantage is not something that other similar products can achieve.
6. Long service life: Because the materials used in the membrane switch have good insulation, heat resistance, folding resistance and high resilience
