FPC circuit membrane switch, also known as light touch keyboard, is a multi-plane combination sealed set of graphics, buttons, and symbols made of soft materials such as PC, PVC, PET, FPC, double-sided tape and screen printing technology. A plastic electronic product that integrates display, conduction and electronic switch functions.

The main features of FPC circuit membrane switch
1. Small and light: The weight of the general FPC circuit membrane switch ranges from several grams to dozens of grams, which is very easy to carry and disassemble.
2. Beautiful: Modern and perfect silk screen technology, with perfect design, can produce any pattern you need.
3. Sealing: The use of unique technology can make the membrane switch have the functions of waterproof, oil-proof, anti-pollution, and anti-static interference.
4. Excellent electrical 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 it is made by special technology The membrane switch can even accept a high voltage electric shock of hundreds of thousands of volts without damaging its function.
5. Low cost: The price of some FPC circuit membrane switch is even a few cents. Compared with a product with such a multi-functional electronic original device, its price advantage is not that other similar products can match.
6. Long service life: because the material used in FPC circuit membrane switch has good insulation, heat resistance, flexural resistance and high resilience; and the pattern printing is reverse printing, so that the silk screen pattern will not be damaged ; Therefore, the service life of FPC circuit membrane switch can generally reach more than three years.
