发明名称 Multifunction fuel sensor
摘要 A multifunction fuel gauge has a rotating wiper assembly turned by a float in a fuel tank, the wiper assembly having two wiper contacts having different radial lengths which make contact with a plurality of contacts which form two concentric arcuate rows on a board. The first row has several contacts connected to a resistive element to provide a voltage signal to a fuel gauge. The second row has at least one conductive strip which has a width such that one of the wiper contacts makes electrical contact with the conductive strip for a portion of the arc transversed by the wiper assembly. This contact can be used, for example, as a low fuel sensor.
