1. A liquid level sender assembly comprising:

  • a housing;

    a resistive track mounted to said housing;

    a pivot arm pivotally connected to said housing for rotation about a pivot axis and having a rotational force transmitting member;

    a contact carrier pivotally connected to said housing for rotation about said pivot axis and having a rotational force receiving member and a contact assembly, said contact carrier, except for said rotational force receiving member, being isolated from touching said pivot arm;

    said rotational force receiving member cooperating with said rotational force transmitting member to receive from said pivot arm only force components directed circumferentially about said pivot axis;

    said rotational force transmitting member and said rotational force receiving member dimensioned such that there is a predetermined arc of travel of said rotational force transmitting member which does not result in contact between said rotational force transmitting member and said rotational force receiving member and;

    said contact assembly electrically cooperating with said resistive track to generate a variable resistance, said variable resistance varying according to an angular position between said housing and said contact carrier.
