ABSTRACT:
The cover of a casing of the potentiometer is formed with an opening which is adapted to be closed by another cover and through which the top surface of a resistor core is accessible. Trimming resistors are located on the top surface and are connected electrically to a resistor path applied on the bottom surface of the resistor core. This permits adjustments of the potentiometer to be made even when the assembly is completed.
