A method for controlling a clutch, especially a double clutch, an interruption-free manually controlled gearbox, especially a parallel gearbox. The pressing system includes: at least one hydropneumatic store and at least one dual-articulation actuating cylinder. A second pair of conductors for carrying a second signal is provided adjacent to the first pair of conductors in the layer, where the first and second pairs of conductors are configured such that cross-talk between the first and second pairs of conductors is substantially minimized, without increasing the size of the package. The three first vibrating electrodes are arranged substantially perpendicularly to the three second vibrating electrodes via the piezoelectric film.
