(Normalling) 100V 0.15A standard switching diode, DO-35Push button switch, generic, two pins D Push button switch with 6 positions D 3 rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one tl074 and support components, so tiny PCB should be 10 nF.
