ABSTRACT:
A variable resistor that employs a bumped or dimpled flexprint circuit that rotates relative to an adjacent ceramic substrate having concentric circular resistors formed with printed resistive ink. The ceramic substrate is fused or screened with the resistive ink in a circular arrangement that forms the plurality of concentric printed resistors. The flexprint circuit having bump or dimple contacts is constructed, and the contacts of the flexprint circuit are positioned facing the ceramic substrate so that contact is made between the individual resistors and contacts. As the ceramic substrate rotates relative to the contacts, the values of the resistors change to produce variable resistor values.
