Abstract

See full text

A control element comprising a support; a control part which defines at least one operating surface, which is movable or elastically yielding if an operating force F acts upon the operating surface; a layer structure that is disposed between the control part and the support and that is elastically deformed if an operating force F acts on the operating surface. The layer structure has at least one first electrode associated with the support and a second electrode, which is associated with the control part and disposed underneath the operating surface, for the definition of a measuring capacity varying in accordance with the operating force. The layer structure further has an intermediate layer having a recess which is disposed between the first and second electrodes for defining a hollow chamber; and means for venting the hollow chamber. The means for venting is integrated at least partially into the intermediate layer.
