A level indicator having a support, a thick-film resistor network arranged on the support, a bow that carries a contact structure that produces, depending on the position of the bow, an electrical signal in the thick-film resistor network, a lever arm that is retained in the bow and has a float on its other end. The float has a seat for the lever arm. The lever arm has a pivoting range in a first plane. The float has a second plane that is perpendicular and that extends perpendicular to the first plane and through the center of mass of the float. The float is mounted on the lever arm to be positionally immobile. The seat for the lever arm is arranged in a region of the float which is arranged on the side of the second plane that faces away from the seat of the bow and that is delimited by the second plane and the outer periphery of the float.
