ABSTRACT:
This invention includes a combustion engine fuel level indication system operable at 10 mA or lower and without any contact resistance buildup. The present system utilizes a noble metal ink formulation for both contacts of resistive path and a conductive path. The resistive and conductive paths each having angled conductor lines which reduce the overall volume requirement for the noble metal ink composition used to make the paths. The invention also includes a wiper contact having spaced apart parallel tangs or fingers positioned so that a first finger engages a first conductor line along the conductive path and a second finger engages an adjacent conductor line along the conductive path to improve the make brake contact.
