Hello
Got a wiring question.
I built a simple 18VDC PS from JameCo and I put it in a project box. I've added
two pots for adjusting power, banana plugs for external power, two mini
voltmeters and will add a USB port for 5VDC. All this works but now I want to
add a AC rocker. The above was simple except for the meticulous care that's
needed to drill into a metal box. Now the next item I want to add is an AC
rocker switch but I'm a bit unsure how. It's a 3 terminal AC rocker, and my
understanding is the bronze terminal is ground, the center is the power source,
and the 3rd one is accessory/load. What confuses me is the proper way to wire
it. If the plug was polarized I wouldn't be confused. I've attached a photo of
the back of the PS which shows the two power supply wires (one with writing and
the other none). The videos I've seen doesn't explain which is power/live and
which is ground using this type of wire. The plug isn't polarized so it's not
easy for me to determine + from -. I put a meter to the wires inside the PS
and it shows 119 and if I switch the probes it still shows 119. What I was
expecting was to see -119 when the probes were wrong and this would've told me
which is + and - but it didn't. So which wire goes to the power source terminal
and which wire goes to the ground terminal? Do I simply wire it by wiring
together the wires with writing and the wires without writing? I hope I've made
sense.
Thanks
