A liquid level sensor is disclosed for measuring the amount of fuel remaining in the fuel tank of a motor vehicle. The liquid level sensor comprises a vertically oriented resistor element (14), a float (16), and a contact assembly (75). A conductive strip (20) and a continuous pad resistive strip (22) are both located on the same side of the resistor element (14). The contact assembly (75) is removably locked in the float (14), and is movable with the float along the resistor element (14). A contact (80) connected to the end of a contact arm (78) of the contact assembly (75) is biased against the conductive strip (20), and another contact (82) is biased against the resistive strip (22). At any point along the resistor element (14), the contact assembly (75) electrically connects the conductive strip (20) and the resistive strip (22) to complete a circuit having a resistance proportional to the height of the float (14) to indicate the level of liquid in the vessel. |
