ABSTRACT:
An n-position selector switch includes a binary counter which is clocked in response to a user actuated push-button type input. The counter's output is fed into a decoder, the output of which drives a visual display indicating the selected switch position. A detector at the counter output responds to a data pattern indicative of selection of the nth-switch position by initiating a counter load operation which resets the counter on the occurrence of the next pushbutton actuation.
