    just try a push on push off DPDT switch from digikey very reasonably priced and considering the wiring you need to do for a proper flip-flop circuit, this shipping cost is quite reasonable.

    Yeah, well I'm gonna build my own lunar space lander! With blackjack aaaaannd Hookers! Actually, forget the space lander, and the blackjack. Ahhhh forget the whole thing!

        LOL like to see that happen... when he's in Germany!

            they have a German site. I assume they have a German warehouse. ( I could be wrong)

                OK, I'll try to make it clear once more: I want a good-looking pushbutton. Good-looking on/off switches plus shipping are too expensive for me, and I think doing it the complicated way would be a good exercise for me as well. I know it's complete overkill and I should just get an SPST and STFU, but I don't want to

                So I need whatever is necessary to emulate an SPST switch through a momentary pushbutton. I know it would have been very very easy if I could just use a real, non-momentary switch.

                OK, suppose I wanted to get these (they are only available as momentary pushbuttons):

                    Would this work? (scroll down to "Single Transistor Relay Toggle Circuit")

                        Use the 'High Current MOSFET Toggle Switch with Debounced Push Button' ckt instead. You really want a debouncer

                            those are some sexy switches!!!

                                Greebe, in the description to the circuit I linked to is stated that this one does not need a debouncer (for whatever reasons) - and it seems to me a little easier and more straight-forward for a beginner like me (It's funny: The switch will be the part with the most discrete circuits in the whole project ) Do you still think the other one would be that much better?

                                Guchi: Yeah, they're sexy (They cost ~15-20 EUR a piece though, which is too much for me Maybe when I build something that's more expensive anyway ) And I hope next year I will finally have started studying, too, and will actually understand a little of what I'm doing
