Start cabinet with single power button, idea help needed (Schematic included)

(1/8) > >>

kelroy:
Hey I think I may have solved the power switch problem or am very close to solving it.  I need people to look at the provided schematic and provide feedback.

*one problem that may arise the relays need to be damn near instantaneous else power will drop.

if you cant read the Schematic  download it the resolution is high enough to read.

The SPST Momentary Rocker/Lever would be the switch mounted on the back of the cabinet.

I feel that the first schematic is flawed and this next one is closer to the solution



I think the key is the momentary dpst momentary switch which I think makes relay #4 and #1 unnecessary

Input please!

TheShanMan:
Could you explain what the power switch problem is? I have no power switch problem that would require something like this. I have a power strip that controls power to all secondary outlets based on current flow in the primary outlet (which powers the computer), so I power on the PC and the whole cab comes to life. And then I just use a regular arcade button as the PC's power button (rather than the button on the front of the PC) to power up and power down.

Is your problem different???

kelroy:
with this you would be able to flip one rocker switch in the back of the machine and the whole thing would power up.  flip the switch again and the computer shuts down gracefully and the power is cut. 

TheShanMan:
OK. I just don't understand why you'd go to all that trouble when a power strip like I have and a momentary pushbutton will do the same thing.

kelroy:
essentially the same thing but this way no one would know the wiser that the heart of the beast was a computer.
