I've read up about reed switch and they seem ideal for the task i need. I know its old technology but its the only solution i can think of, I'll describe this problem after my question about reed switchs though. What i want the reed switch to do is act as a switch for my circuit so i will put it right before the supply, before any other components meaning if its open no current through the entire circuit. I donno if this is seems they can only hand low currents or am i mistaken and will i be able to do this. i haven't figured out my current reading yet but my supply voltage will be 9v using a simple 9v battery. That's the question. The problem is i want to power a circuit that needs to run until its function is complete and shut off completely drawing 0 current from the battery, this function is activated by a one of those click buttons that have a spring so they are only in contact when they are being pressed(don't know formal name). My solution was a flip-flop to keep the reed switch on while the circuit is running and reset it when the function has finished. is there a newer or simpler solution?
