Abstract:
1. A potentiometer, having (a) a first electrically conductive segment which has a first contact side which is delimited by a first circumferential edge; (b) at least one second electrically conductive segment which has a second contact side which is delimited by a second circumferential edge; (c) wherein said first contact side and said at least one second contact side are situated in a common plane; (d) wherein said first and said at least second electrically conductive segments form a closed arrangement in which each segment has exactly one neighboring segment to each side and wherein an electrical contact is arranged between two neighboring segments; (e) a connecting apparatus rotatable about an angle of rotation and electrically connecting a first contact point on said first contact side or on said at least one second contact side to at least one second contact on said first contact side or on said at least one second contact on said first contact side or on said at least one second contact side; (f) an electric energy source that is connected to at least two electrical contacts so that an electric current flows through all segments; and (g) a voltage ascertainment apparatus that is connected to at least two of said electrical contacts to measure at least one voltage which depends on said angle of rotation so that said angle of rotation is derivable from said measured voltages.
