Abstract
A rotary switch includes a plurality of first electrical contacts disposed at a common radius and a plurality of second electrical contacts mounted for rotation against said first electrical contacts at said common radius. The first electrical contacts include at least one contact representing a selectable logic level and other first contacts electrically isolated from the at least one contact. The second electrical contacts electrically couple the logic level contact(s) with a unique combination of the isolated contacts in each of the respective switch positions.
