Excellent ! Thanks Hero.

Hi Hero, thanks for replying ... There's a schematic at the bottom of the link i posted, what i'm hoping is i can connect GND to X3-2 (relay common) and then put the fan between X3-3 (relay n/o) and the +12V (or put the fan between GND & X3-2, and connect X3-3 to +12V )

Hi all, I've just built this kit with which i'd like to control a 12v car fan (the type that plugs into the car's cigarette lighter) .... Could i use the same 12v dc supply which powers the circuit to power the fan, just using the relay in series to switch the fan on & off ? Or will that short out something ? Thanks folks !
