Hello, I have a simple question (I am not an expert on electronics and electronics components).
I have a micro-switch that is acting as a power supply on button for a PC motherboard, however, for the board to function correctly, a seperate 12V DC supply must be plugged in first (as it provides power for hard drives and so on, that the mainboard uses)
1) Is there a way that I can have the micro-switch so that it cannot complete the "power on" circuit if the 12v supply is not connected (pressing it would just do nothing, forcing the other power connector to be plugged in first)
2) Is there a way to have power to the mainboard cut off immediately if the 12v power supply goes off for any reason (for example, accidentally pulling out the DC plug)
Any help would be appreciated, I can wire up a basic circuit, but I don`t have any idea how to solve this particular problem.
Thanks!
