What is the membrane switch
Film Switch also known as the light Touch keyboard, is the use of soft materials such as PC,PVC,PET,FPC and double-sided glue, the use of screen printing technology produced by the multi-plane combination of sealed set graphics, keys, marking symbols display, conductive and electronic switch functions in one of the plastic electronic products.
The main characteristic of the film switch is the following characteristics.
1, compact and lightweight: The general film switch weight for a few grams to several decades, very easy to carry and disassembly;
2, Aesthetics: Modern perfect silk screen technology, with the perfect design, you can make any design you need;
3, sealing: The use of unique technology, can make the film switch with waterproof, oil, pollution prevention, anti-static interference and other functions. 4, good conductive performance: The switch circuit can be used carbon paste, silver paste, copper and other printing, conductive layer can be folded freely, and resistance can be controlled. In any resistance you want to need, and with a unique technique, the film switches made of the A hundred thousand of KV can even accept a high voltage electric shock without damaging its function.
5, low cost: Some thin film switch price even only a few cents, compared to a product with such multi-function electronic device, its price advantage is not the other similar products can be matched.
6, Long service life: Because the film switch used materials have good insulation, heat resistance, flexural resistance and high resilience; and the printing of the pattern adopts reverse printing, so that the screen printing pattern is not impaired; So, the film switch service life can be up to three years.
