Control device with shielding

The invention relates to a control device (10), having a circuit carrier (14), having a plurality of series arranged in the region of a circuit carrier (14) or of a connection body (17) connected to the circuit carrier and of a plug connection body (12), said series each having a plurality of first and second electrical contact elements (26, 27, 36, 38; 38a; 72, 76), which are arranged next to one another in the series and which serve to make contact with the circuit carrier (14) or the connection body (17) and from mating contacts (28, 29) of a plug (100), wherein the first contact elements (26, 27) serve for signal transmission and the second contact elements (36, 38; 38a; 72, 76) serve to form an electromagnetic shielding (40; 70) for at least one first contact element (26, 27).
