Abstract
A rotary switch convertible from being operable over a smaller range of angular motion, e.g. as a two-position switch, into being operable, in either of two configurations, over larger ranges of angular motion, e.g. as a three-position switch. A rotor and a stator are assembled for relative rotation. Four lugs divide a face of the stator into four quadrants. Two pairs of lugs, each comprising a removable lug and a permanent lug, are provided on a face of the rotor. The faces are juxtaposed such that relative rotation of the rotor and the stator is limited by interference between certain of the lugs on the rotor and certain of the lugs on the stator. Before removal of either removable lug, the rotor and the stator may be assembled for a smaller range of angular motion. After removal of both removable lugs, the rotor and the stator may be assembled in either of two configurations for larger ranges of angular motion.
