ABSTRACT:
A resistor card for a fuel tank level sensor configured to reduce wear between an electrical contact wiper and metalized conductor pads formed on a substrate, by the deposition of thick film resistive material on the individual pads. The resistive material forms a protective coating on the pads to protect the metalized pads from excessive wiper wear.
