摘要

The membrane keypad has a base (2) in the form of a carrier foil, a metal base plate as a base surface and a front foil as a cover surface. A switch foil (9) has a switching unit (1) e.g. snap disk, and an illuminable surface over the switching unit, where the illuminable surface is formed from a section in a spacerfoil (6) that is provided between the base plate and the front foil. A flat lighting element (5) e.g. organic LED, is arranged in the section to illuminate the entire surface.
