Zusammenfassung:	The operating unit comprises an actuator, which mechanically excites an operating element. The actuator comprises a support strip made of a resilient material. Piezo elements, which are connected to the support strip in a shear-resistant manner, are located on both outer surfaces of the support strip. As a result of the alternate arrangement of the piezo elements, the support strip assumes an undulating form when moving out of its inactivated state. One side of the support strip is mechanically connected to the operating element and the other side is mechanically connected to a counterbalance. The support strip itself is mechanically fixed in the housing. In its inactivated state, the operating element and the counterbalance are at a different distance from one another than in the undulating activated state, wherein they move in opposite directions and thus lead to a compensation of dynamic forces acting on the housing.
