This patent describes a position indicating device for producing an indication of the position of a displaceable structure comprising: a position representing member mounted for movement in response to displacement of the structure; sensing elements spaced apart along the defined path such that each element is associated with a respective location along the defined path; means operatively coupling the elements into respective pairs of elements, having, for each pair of elements, an output producing a signal only when a single element of its respective pair is responding to the presence of the member; signal producing members each operative for producing a signal representing a predetermined logic state in response to a predetermined input signal, the number of the signal producing members being smaller than the number of the sensing elements; and circuit means operatively connecting the outputs to the signal producing members for causing a signal at each output to produce a predetermined input signal at a corresponding signal producing member and for causing a predetermined input signal to be produced at least one the signal producing member whenever a signal is present at either one of at least two of the outputs.
