Pneumatic control unit for controlling a pneumatic pressure comprising: - a housing, - at least one actuator (1, 1a) configured to be manually moved along a total distance within the housing and configured to control a pneumatic pressure depending on its position on the total distance, and - a locking mechanism configured to lock the at least one actuator (1, 1a) in at least one locking position along the total distance, wherein the locking mechanism is configured to release the locking of the at least one actuator (1, 1a) if at least one release condition is met, wherein the at least one release condition is met if a force or torque acting on the at least one actuator (1, 1a) especially along the total distance exceeds a predetermined release value, wherein the locking mechanism is configured to lock the at least one actuator (1, 1a) by applying a magnetic locking force, wherein the magnetic locking force is applied on the at least one actuator (1, 1a), wherein the pneumatic control unit further comprising: - a guidance extending along the total distance and - a counterpart guided by guidance, wherein the counterpart and the guidance are configured to be relatively movable against each other when the at least one actuator (1, 1a) is moved along the total distance, and the guidance is configured to apply an inhibit force or inhibit torque on the at least one actuator (1, 1a) and/or to lock the counterpart in the at least one locking position on the total distance, wherein the guidance comprising a tapered portion with a smaller aperture than the maximal extension of the counterpart guided in the guidance, and the tapered portion and/or the counterpart are/is configured to deform elastically, when the tapered portion and the counterpart are in contact by a force or torque which exceeds the predetermined release value. - a housing, - at least one actuator (1, 1a) configured to be manually moved along a total distance within the housing and configured to control a pneumatic pressure depending on its position on the total distance, and -
