Abstract
A component assembly, for constituting an electrical part such a volume unit, having a pair of appropriate components, such as those approximate to each other in electrical characteristic, joined as a unit by a connecting plate. In use, the pair of components are separated by severing the connecting plate and are then coupled together to provide the electrical part.
Claims4
A component assembly to be used in assembling an electrical part having a pair of resistor components controlled by a single shaft with sliding contacts thereon each contacting a respective one of the resistors, comprising:
- a pair of similar resistor components each having a base on which a resistor surface is formed and a frame formed integrally with the base, wherein the frames of the pair of similar resistor components are joined together by a connecting plate, and their resistor surfaces are formed under similar conditions with the frames joined together so that the resistor surfaces have similar electrical characteristics, whereupon said connecting plate can be severed and then separated, similar resistor components having similar electrical characteristics can be assembled as the resistor components for the electrical part, in order that operation of the single shaft can result in a similar response from each of the assembled pair of resistor components.
