Piezoelectric actuator system

The positioning system includes a piezoactuator (14). The links between the piezoactuator and a transmission lever (16) are provided as rolling butt contact forming a line contact. All line contacts run in parallel. The transmission lever is preloaded by a spring (42) and a switching pin (12) is cushioned by a further spring (44) with respect to the transmission lever. The axis of the switching pin touches the lever radius in its fulcrum.
