Abstract
Abstract An electrical multipositional switch arrangement is disclosed having a rotatable switching wheel and at least one stationary circuit board or plate possessing contact tracks for the purpose of generating switching signals in accordance with a predetermined code as a function of the position of the switching wheel. The switch arrangement includes connection elements mounted between corresponding contact tracks, these connection elements being actuated according to the predetermined code in dependency upon the position of the switching wheel by switching means which do not come in contact with the connection elements.
