Disclosed is a coding switch comprising at least two conductor paths each having a plurality of contact points disposed on a circuit board about at least a portion of a circle, the circles about at least a portion of which the contact points of the respective paths are disposed being coaxial, and a wiper having at least two spaced and electrically connected contact points secured to the circuit board to rotate about the center of the coaxial circles so that each contact point of the wiper can come into electrical contact with the contact points of a respective conductor path. The wiper is preferably provided with a handle at an end thereof outwardly of the center of the coaxial circles for manually rotating the wiper. The wiper can be set without setting apparatus such as setting rings and the like and the handle can be moved, even from a distance, by a pencil, for example.
