Abstract
Switch apparatus having a digital display is provided in accordance with the teachings of the present invention. The switch apparatus according to the present invention includes an encoder having a code pattern thereon which is scanned by a reader to produce multi-bit binary information to be displayed. A storage circuit having switch positional information stored therein is also provided and a collator is employed to compare the multi-bit binary information read by the reader with the positional information stored in the storage circuit. When a comparison is obtained a braking force is applied to inhibit scanning so that a switch position corresponding to stored positional information is obtained.
