ABSTRACT:
A variable resistor having an insulating substrate, a resistive film applied to the surface of the substrate and spaced terminals supported by the resistor and in electrical connection with the resistive film. The resistance of the film is adjusted by means of scribing to remove portions of the film to provide a means of isolating certain areas of the film to increase the resistance of the electrical path between the terminals. Embodiments of the assemblage are disclosed wherein the scribing tool may provide an arcuate configuration or a linear configuration to provide desired resistance values.
