ABSTRACT:
An electric level sensor for motor vehicle fuel tanks comprises a potentiometer for continuously monitoring the level, which is constituted by an arcuate resistive track deposited on a ceramic plate and a resilient movable contact blade fixed for rotation with a pivoted arm which carries a float. When the level corresponds to the reserve fuel level, the movable blade is arranged to cooperate with a fixed contact constituted by an electrically conductive area formed on the ceramic plate near one end of the resistive track. The blade has a pair of studs for making contact with the track and the conductive area respectively.
