Abstract
A variable resistor assembly is preferably adapted for use with a fuel level sensor and includes an arcuate resistive area including a plurality of radially oriented and spaced apart conductive contact segments, and further includes a wiper including an arm and at least two contactors carried by the arm, wherein the at least two contactors are arranged on the arm such that the at least two contactors make contact with one of the conductive contact segments before breaking contact with an adjacent one of the conductive contact segments. Preferably, the at least two contactors are laterally offset with respect to one another and/or oriented at an angle with respect to the conductive contact segments.
