I'm converting an old ATX power supply to a benchtop supply. Overall, a very easy project, but I wanted to add a lighted power switch - http://www.radioshack.com/product/index.jsp?productId=2103602
The power supply is switched when the power supply (green wire on mine) is connected to ground. I placed these at opposite ends of the switch and the power is on/off appropriately. I attached the 12V wire to the center pole of the switch and the power supply fan slows to nearly off and the switch light flickers dimly. If I connect the green directly to the ground pole while the switch is on, the light comes on appropriately and the fan runs correctly. Switching the switch off works correctly too, but when I turn it back on...nothing. What, if anything, am I doing wrong? I've wired other ATX supplies with simple toggle switches with no problem. Am I just not able to use a lighted switch?
