Abstract
A trimming potentiometer in which three parallel resistance paths are located in a plane on an insulating plate. Wiper contacts are displaceable in the same direction on the resistance paths, and are attached to a common carrier which is longitudinally displaceable by a threaded spindle. Inductance loops are arranged between the resistance paths and the respective terminals for the paths, for the purpose of matching the trimming potentiometer to its inductance and capacitive input and output values.
