Hi all! I'm working on a self-contained project that will be battery powered. I want it to come "on" when the user presses a pushbutton, but then turn "off" again after, say, 10 minutes of inactivity. This device must be very power conservative, because it won't be very feasible to swap out the 9V…

ON and OFF (and sleep?)

The switch will hold power on until the Arduino is up and can power the relay to keep the power on.
