1. A liquid level sensor for use with a container, comprising:

  • a housing including a body defining an interior volume;

    a switch actuated by an applied magnetic flux field to a closed position, the switch being disposed within the interior volume of the housing;

    a float including a body, a first end and a second end opposite the first end;

    a pivot assembly pivotably coupling the housing and the first end of the float such that the float is pivotable about the pivot assembly between a first position and a second position;

    a magnet disposed within the pivot assembly; and

    a shunt disposed within the first end of the float body,wherein the shunt is disposed between the magnet and the switch in the first position of the float, thereby shielding the switch from the magnetic flux field of the magnet such that the switch is in an open position.
