Is there a way to circuit a power efficient toggle switch controlled by a SINGLE button so that absolutely no current from the power source is drawn at it's
OFF state and hopefully but not exactly necessarily, minimal current is drawn on its
ON state. So far I got this...
It consumes no power when
OFF and when pressed the led turns
ON. I couldn't figure out the turning off bit.
Also don't suggest me to use a button that mechanically toggles. I know that exists, but I don't want to use that.
Additionally I do not want to use normally-closed/double-throw buttons and normally-closed/double-throw relays (which means I only allow the normally-open version of these components). If your solution requires those component variants however, I wouldn't mind for you to post them.
