Abstract
A filling level indicator includes a retainer, a bow rotatably supported on the retainer and having a lever arm fastened thereto, a float fastened to the lever arm, and a filling level sensor arranged in the retainer. The filling level sensor has a substrate, a resistance network arranged thereon, a contact spring structure, and a cover, connected to the substrate, that covers the resistance network and the contact spring structure. A magnet is connected to the bow or the lever arm and acts on the contact spring structure such that an electrical signal corresponding to the filling level is generated according to the pivoting range. The mount has a wall thickness that can be penetrated by the magnetic field of the magnet, and so metal particles are held on the outside of the mount by the magnetic field of the magnet.
