@SawMaster: Wow, thank you very much for the drawing and the detailed explanation. It looks like its exactly what i was hoping to achieve. Thank you very much for the time and effort you put into doing this for me
I had a good look at it, and tried getting my head around the switch details, but i got a little sidetracked regarding you mentioning i should remember this is the underside of the switch....... then i tried double guessing which way it was flipped.......... but just to make sure i get it, is this understanding of the switch wiring correct?
On the left side: 12v is passed into pole #2 which activates pole 3, this then travels to a cig lighter contact and converter to pole 6 as 5v. Pole 6 being energised, activates pole 5, sending 5v to power the camera.
On the right side of the switch, 5v activates pole 4, sending 5 v to pole 5 and up to camera.
Is that a correct understanding of it?
My next question is, is the supplied 12v cig plug with converter, safer, more reliable, better longevity than the 12v converter attached to a hardwire kit? and, everything else being equal, couldn't i use the hardwire kit to convert to 5v before entering the switch from the ACC on pole 2, and simply loop or bridge 5v from pole 3 to pole 6 directly, cutting out some bulk?
Many thanks Phil.
