A rotary-type switch simulator includes a shift register and a counter, both clocked by a momentary contact switch. The shift register outputs drive visual indicators indicating the selected switch position, while the counter provides a binary output corresponding to the indicated switch position. Logic circuitry, responsive to selected data bits at the outputs of the shift register and counter, reset the shift register and counter respectively to their initial states after the highest switch position has been accessed.
