1. A fluid level sensor comprising:

  • a frame;

    an arm pivotally mounted to the frame at a first end of the arm;

    a buoyant member attached to the arm at the second end;

    a cam attached to the arm at the first end at a pivot point;

    a contact arm abutting the cam;

    a resistor card attached to the frame having conductive traces adhered thereto that are aligned parallel to one another along the length of the resistor card; and

    a contact finger attached to the contact arm, wherein upon movement of the arm the cam rotates around the pivot point causing the contact arm to move and causing the contact finger to slide along the conductive traces of the resistor card in order to provide a change in resistance value.
