Abstract
A water level sensor device of a fuel filter may include a printed circuit board and a water level sensor composed of electrically conductive plastic. The water level sensor may be coupled to the printed circuit board via an electrically conductive metal element. The metal element may be coupled to the water level sensor via a press-fit assembly. The metal element may include a sharp-edged fastening contour configured to tear open the plastic of the water level sensor when the metal element is pressed against the water level sensor.
