Abstract:
A variable resistor card for use with a wiper to form a potentiometer, said resistor card comprising,a non-conductive substrate, a plurality of conductive lands in spaced relationship on a surface of said substrate, each of said contact lands having a resistor end and a contact end and a height above said substrate, said contact ends oriented to form a wiper track, a resistor between each successive pairs of said resistor ends of said conductive lands, a filler between said contact ends along said wiper track, said filler not extending over an upper surface of said contact ends wherein said filler and said conductive lands are alternately engagable by said wiper as said wiper moves along said wiper track, and said filler being one of an insulating material and a highly resistive resistance material.
