Abstract
A compact configuration of resistive elements, plural circularly-arranged fixed contacts upon, or mountable upon, a printed circuit board (PCB), to comprise a rotary variable resistor. In one embodiment, fixed contacts are disposed upon one side of a PCB, in which through-conductors connect to a resistor pattern upon a separate ceramic substrate. In another embodiment, fixed contacts occupy the central area, and resistors and interconnecting conductors surround the same; all on one side of a ceramic substrate. Mutually insulated spring wipers connect to the fixed contacts to allow rotary variation of resistance.
