it concerns power button(or power on/off). i've heard one can go the hardware route and use an S-R flip flop eg. 74C74 and use the output to enable/disable the voltage regulator. i.e the 74C series (and the CD4000 series) can take up to 15V supplies, so one could power them from the input to the regulator.
could one provide the circuit setup/wire up of this?
i would highly appreciate your help guys!

I must still be missing something. You can get latching SPST push button switches anywhere. That would give you push-once-for-on/push-again-for-off operation.
Do you mean you must have an electronic switch configuration instead of a nice, simple electrical one? If so, why?
