An electric operating part assembly has a switching mat and switching mat domes which are arranged therein and which can be operated by the effect of a vertical force. In one embodiment, the uncommitted target data from instructions being run-ahead executed may be saved into an advance data table. The first switching element is connected with a data channel of a data driving part. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The drain of the PMOS transistor can be connected to a positive end of the fuse.
