Abstract
A device for indicating the level of the axle of a vehicle having a reference mark indicator which follows the level of the vehicle axle is arranged fixedly connected on the axle of the vehicle and changes its position as a result of the change in level. An electric signal which corresponds to the level of the axle is obtained from a resistance network which is firmly attached to the body of the vehicle. In a level indicator which operates with little wear, is economical to manufacture, and nevertheless is of high accuracy, the resistance network has, associated with it, a contact structure which, under the action of a magnet device which is movable by the change in position of the reference mark indicator, can be deflected in the manner that an electrical connection which is dependent on the level of the axle is produced.
