Patent ID: 8742647

Claim:
A control mechanism for an electrical appliance comprising: a control panel that is deformable or elastic, whereby at least one piezo sensor element is arranged under said control panel, wherein the at least one piezo sensor element is arranged on the rear side of a printed circuit board with the opposing front side of said printed circuit board attached or fastened in a planar manner to the underside of the control panel, wherein said at least one piezo sensor element comprises a piezo ceramic disk that is bonded to a metal membrane, said piezo sensor element having a planar electrical connection on its upper side, as well as on its underside, wherein contact pads with contact leads connected thereto are provided on the printed circuit board, and said at least one piezo sensor element is fastened in a planar manner for electrical contact on the connecting field to the printed circuit board in an electrically conductive manner, and wherein the piezo ceramic disk faces the printed circuit board and is in direct contact therewith as a one-sided contact instead of as a two-sided contact.
