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. USE - Used with an electronic circuit. ADVANTAGE - The illuminable surface of the switching unit is formed from the section in the spacerfoil that is provided between the base plate and the front foil, thus enabling to produce the membrane keypad without an established and tested structure and with only slight increase of the thickness of the membrane keypad.
