The control arrangement is equipped with a compressed air source, at least one leveling valve (15), with air suspension bellows (24) assigned to at least one vehicle axle, a switching valve (8) and an electric switch (1), which permits controlling the positions Stop, Raise, Lower and Drive. The switching valve (8) is electrically driven by two solenoid valves (6 and 7) and connects or interrupts the different pneumatic lines as is common in the art. With a no-pressurized switching valve (8) and/or non-energized solenoid valves (6, 7), however, the respective pneumatic lines (17, 18) from the switching valve (8) to the leveling valve (15) on the one hand and to the air suspension bellows (24) on the other hand are closed off. The positions Raise, Lower and Drive are assigned to the three activated positions of the two solenoid valves (6, 7).
