Run/stop (sw14) // 1 for 5v / 2.5v output mode (sw12) // 1 for once/cont (sw15 // 2 NO Moment switches: // 1 rotary switch, 5+ positions 6 sockets Potentiometers: One potentiometer for internal clock rate. Switches: Momentary-normal-off pushbutton to manually step. SPST switch per step, to set output voltages. (10) One potentiometer for internal clock signal (possibly external).
