To the Electrician - I shared the simple circuit you proposed here and got the following input:
"The circuit that you linked uses a PNP transistor--the best PNP is rated at 5A and has significantly higher Vce sat."
Not sure I understand but I take it that perhaps the use of a NPN transistor may be more advantageous? Your comment was pretty clear on this one having a low Vce sat and as I'm a lightweight in all things electronics you can imagine I'm a bit confused by now... How does the transistor's saturation mode affect my design? Are we talking about threshold or loss of forward current?
Again, please forgive my obvious ignorance.
