    Abstract: Multi-impedance electrical component having an impedance selecting means assembled with at least one circuit wafer supporting a plurality of operationally discrete film type impedance elements, i.e., film type elements supported in groups on the wafer to form a single integrated mechanical structure, the film type impedance elements being useful in an electrical circuit in lieu of structurally independent resistors, capacitors, and inductors. Film type conductive interconnectors are connected with the operationally discrete impedance elements and a conductive contactor forming part of the impedance selecting means is movable to different contact positions for completing an electrical connection with selected ones of the conductive interconnectors. An indexical detent mechanism cooperates with a shaft for selectively changing the position of the conductive contactor, operation of the shaft causing one or more of the operationally discrete impedance elements to be connected in a circuit between termination points on the wafer. The wafer is formed of heat resistant material, and the operationally discrete impedance elements are formed from film type material and are precisely adjusted to a nominal impedance value by removing portions of the film from the surface of the wafer.
