It started out with a modding accident, and I ended up cutting the yellow cable of my cases power switch. I then installed an SPST switch (looks like a missle launcher flip switch) by in essence splitting my wire. I soldered a three inch peice of that yellow wire to one end of the switch and one end of the button, then soldered the black wire to the momentary button and the yellow to the switch. They both lead to the cable end which is plugged in properly to my motherboard.

Does anyone have any idea as to why this does not work?
