1. A signal transmitter for a fill level sensor of a container of a motor vehicle configured to produce electric signals as a function of a fill level, comprising:
a resistor arrangement,
a conductor path arrangement having a slideway and arranged on the resistor arrangement and connected to the resistor arrangement, and
a sliding contact configured to move in accordance with the fill level and slides across the slideway of the conductor path arrangement,
wherein the resistor arrangement and the conductor path arrangement at least partially overlap,
wherein the resistor arrangement defines at least one material recess arranged between two sections of the resistor arrangement that are covered by two mutually adjacent conductor path sections.
