Abstract
Abstract A binary coded readout device has a printed circuit pattern on a circuit board with conductive segments in adjoining sectors which are wiped by contact members on a rotating wiper. There are two angularly spaced wiper contact positions per sector in the outer circle of contact member travel. The rotating wiper has an axis of rotation which is eccentric to its symetrical center and the contact members on the oppositely extending long arms are thus angularly spaced so that with each step of the wiper one of these contact members will come to rest on the clockwise first of these two contact positions in sector N and the other contact number will come to rest on the clockwise second of these two contact positions in a clockwise advanced sector N+4.
