Quick Answer

A membrane keyboard is a cheaper alternative to mechanical keyboards. It has a protective layer of plastic or silicone that protects it from gathering food crumbs and dirt between the keys. Plus, they do not make that irritating clicking sound every time you press a key.

A membrane keyboard is a flat surface of keys. Under this flat layer, there is an integrated circuit system. When you tap on a key, the electric circuitry is activated, and the signal is sent to the processor. As a result, you see the characters displayed on your screen.
