A variable voltage divider having a ceramic substrate supporting a plurality of resistive paths and comprising an arcuate resistive path disposed between two fixed resistive paths, the fixed resistive paths being abraded to achieve a proper resistance ratio between each of the two fixed resistor paths and the arcuate resistive path, a plurality of terminations, a center collector, and a driver mounted in a center aperture in the substrate and carrying a contactor, the contactor wipingly engaging the collector and the arcuate resistive path. The ceramic substrate is enclosed in a housing and contains registration means for locating the substrate in the housing, the two fixed resistive paths being arcuately disposed about said registration means.
