 What you posted was not a circuit... it was not something you could
wire up and expect to work in any way. And that's a professional
opinion, Jason.

 Duh. A series switch and catching diode? Why didn't you just say so?
It's not a practical circuit. What happens if your transistor shorts
out? You get 12V straight up the output jacksie, is what.

 When I was a young lad just starting out, I told an engineer how 
to design circuits and he said, "Don't teach your grandmother to suck
eggs." It took me a long time to work out what he meant. After you've
actually sucked a few eggs, it comes to you...
