I'm building a radbox and using a mains powered 13.8v PSU to power it.
I would like to have the option to run it stand-alone or switch it into relay mode so the 12v line from the PC can turn it on. I'm aware I need a relay for this, but not sure of the wiring required.
My idea was to have a mains switch and a second switch that will toggle between the relay or bypass it, allowing the mains switch to turn the radbox on or off.
I believe the current mains switch in the 13.8v PSU is a DPST (it has 2 x live wires and 2 x neutral wires).
Any diagrams appreciated!
EDIT - OK I've done some googling and found a few mains pumps / 12v relay guides. I'm sure I can work from there.
