Abstract

A piezoelectric bending transducer comprises a flat, electrically conductive supporting body having piezoceramic coatings on both sides. Each coating has an inner contact area facing the supporting body and an outer contact area facing away from the supporting body. The piezoceramic coatings are omitted from one end of the supporting body, which is fixed in a connector base. Each of the two coatings and the supporting body are electrically connected to a plug-in contact that includes an electrically conductive elastomer in a cavity in the connecting body. The elastomer is partially elastically deformed by a contact pin inserted thereinto. As a result of the ease with which electrical connections can thus be made to the transducers, this arrangement is particulary adapted for incorporation into a transducer module with plural transducers secured adjacent to each other in a common connector base. The transducer module in turn is particularly adapted for use in a control module because of the easy interchangeability of the transducer modules.
