Patent ID: 7640800

Claim:
A filling lever sensor assembly comprising: a lever arm; a float at one end of the lever arm; a clip composed of an electrically conductive plastic at another end of the lever arm configured to hold the lever arm, a carrier comprised of plastic; a bearing, arranged on the carrier, configured to mate with at least one of the clip and the lever arm; a filling level sensor arranged on the carrier comprising: a lid; a substrate; an electrically conductive contact face arranged on an outer surface of the substrate; a resistance network arranged on an inner surface of the substrate and to which a contact structure is assigned, an electrical connection of the contact structure to the resistance network producing an electrical signal indicating a filling level as a function of the pivoted position of a lever arm; and at least one permanent magnet arranged on the clip and has the purpose of activating the contact structure, wherein an electrical contact is electrically connected to the clip such that as the lever arm pivots on the substrate said contact describes a circular path corresponding to and electrically connected to the electrically conductive contact face, the electrically conductive contact face is electrically conductively connected to a connecting line of the filling level sensor to discharge an electrostatic charge.
