Abstract

A keyboard comprises a base plate having conductor paths and contact areas provided thereon, a plurality of keys associated with said contact areas, said keys consisting each of an elastically deformable snap member, the contact element thereof being adapted to be brought into contact with said contact areas by deformation upon actuation of an actuating button and being positioned above said contact areas in spaced relationship thereto. A metal frame is provided as mounting support for the snap members, said metal frame having a number, which corresponds to the number of snap members, of protrusions protruding therefrom in a direction toward the actuating buttons. Each protrusion has an opening therein, in which the snap member is held.
