I made a 12V/24V power supply from two HP PSs. I installed an ON/OFF switch on the little wires I used to connect the three little pins of each PS and it worked fine. Then I decided that instead of having two power cords (one for each PS), I wanted the two to merge as one so I did that. I made sure to have one PS grounded and the other ungrounded. So now the switch doesn't work. Is there a way of wiring the switch so it can turn the power supplies on or off when the two power cords are merged together.
Thanks
Oh yes, the pics. Some in here like pics. I went for the compact look.
