Glossary: Membrane keyboard

A keyboard for electronic devices that has no moving parts - typically it is printed using silver inks. A flat, usually programmable, keyboard with numerous pressure sensitive switches located under a soft surface. After areas of the keyboard have been defined, the user activates them by pressing on the surface. Therefore, a membrane keyboard is one flat surface. The advantage is that you can make overlays which customize the layout to fit your specific needs. The disadvantage is that it is only two dimensional, and it can be easy to activate undesired fields without a key guard.
