Abstract

A filling level sensor having a lever arm which has a float at one end and is held at its other end by a clip. A resistance network is arranged on a substrate and to which a contact structure is assigned, the resistance network producing an electrical signal for the filling level as a function of the pivoted position of a lever arm. The clip is composed of an electrically conductive plastic and has an electrical contact connected to the clip in an electrically conductive way, such that as the lever arm pivots said contact describes a circular path on the substrate. The area on the substrate over which the electrical contact passes is an electrically conductive contact face and is electrically conductively connected to a connecting line of the filling level sensor.
