A rotary switch rotates about an axis which is at acute angles to a lower cartridge surface and a cartridge end so that a first display surface and a second display surface may be independently accessed by disparate components residing in disparate planes. The display surfaces are generally orthogonal to each other and can have multiple facets, with each facet containing a subset of information. To aid this optical interrogation, the display surfaces may be generally orthogonal to the disparate interrogating components.
