Abstract: A sensor is disclosed that fits in a compact package. This compact sensor is ideal for sensing rotary positions and for accommodating one or more potentiometers. The resistor track is parallel and opposed to the collector track, and the wiper is placed between the two tracks to swipe both of them in one embodiment. This allows a short package, because the tracks are opposed to each other rather than being in a line, and a narrow package, because the tracks are not placed side by side. Another advantage of the invention is that putting the resistor track on a larger radius and the collector track on a smaller radius allows the resistor track to be longer. Having a longer resistor track allows a higher resolution, yet a package containing the potentiometer will still be relatively small. Several potentiometers may be placed in the sensor to provide redundancy yet retain compactness.

Also, this makes it possible to reduce the kinds of bending operations that must be performed on the terminals.
