ABSTRACT:
A keyboard comprising at least one flap forming a key, the flap being pressed against a contact point when depressed from above, and rising back after the depressing. The flap is attached by its one end to the frame sheet of the keyboard in such a way that this structure forms the hinge of the key. There is at least one buckling member in connection with the flap, and the flap is formed rigid. The keyboard may be formed in such a way, for example, that a keyboard frame sheet is formed, the flap forming the key is cut partially off the keyboard frame sheet, a buckling member is formed in connection with the flap, and the flap is lifted upwards from the surface of the frame sheet.
