You mean like a heavy'ish book on a N.O. P.B.?Only if you use the cheap stuff! But the way I see it, if we are going janky we might as well go full jank.

Epoxy a fender washer centered on the switch and put an N52 NIB magnet on top.You mean like a heavy'ish book on a N.O. P.B.?
I have transistors, but only BJTs.Surely a transistor and 2 resistors will do the same thing? If I understand the requirement, PS_ON needs to be kept grounded except when a reset is necessary. ssr215 do you have any transistors? A BD139 or similar? Within reason, anything will do.
Give us some of the types that you have - BJTs are fine. As I recall, ATX PSUs have a permanent +5v available to enable the Mobo to power up (am I wrong?) that could be used?I have transistors, but only BJTs.
The reason he needs the switch is to reset the supply if it shuts down. It might keep the 5V going but it seems unlikely.Give us some of the types that you have - BJTs are fine. As I recall, ATX PSUs have a permanent +5v available to enable the Mobo to power up (am I wrong?) that could be used?
Just to be clear, you want the ATX psu to be on all the time, but if it DOES trip out for some reason, you want to be able to press a normally open push button (NOPB) switch to turn it back on - is that correct?I want to make a "Reset" button for my repurposed ATX PSU that cuts the jump between PS_ON and GND when pressed (to reset protection mechanisms). How do I do so?
Understood. Actually, I knew that was what you wanted from the very start.Just to be clear, you want the ATX psu to be on all the time, but if it DOES trip out for some reason, you want to be able to press a normally open push button (NOPB) switch to turn it back on - is that correct?
I guess that makes the circuit *really low power*I just realized the fatal flaw in all proposals except purchasing the correct switch: the PS is not available to power anything.
