Abstract
The invention relates to a keyboard and to a method for producing a keyboard for activating electrical switching functions, comprising: a first substrate having a first contact structure; a second substrate having a second contact structure, and; an intermediate layer that holds both contact structures at a distance from one another and enables a contacting of both contact structures when pressure is exerted upon predetermined areas of the keyboard. Both contact structures are imprinted by means of a mass printing process.
