Passive magnetic position sensor

A filling level indicator for determining a filling level in a tank includes: a resistor network; a contact element arranged spaced apart from the resistor network; and a magnetic element movable relative to the resistor network and the contact element. The contact element has a contact region deflectable by the magnetic element. The contact region is deflectable so as to produce an electrically conductive connection between the contact region and the resistor network. The contact region comprises a planar tape-shaped element that is partially deflectable by a magnetic force of the magnetic element. The contact region has at least two portions that are arranged mutually adjacent to, and mutually spaced apart from, one another.
