@Goeytex: Jeepers, your voltage & current numbers are surprising and disappointing. Sounds like an awful lot of internal resistance on the output pins. Makes me wonder if you could even damage an output by shorting it to ground. Now where did I leave my paper clips...?
As I mentioned previously, I have used latching relays sucessfully to provide auto power-off using direct connection to uC I/O pins, although I was using a BASIC Stamp 2. That is also PIC-based, so I assumed a PicAxe would behave similarly. I'm away from home for a few days but when I get home I'll do some tests. Thanks for posting your findings.
