Power Supply Wires

[jp1114]

A friend of mine asked me why there are 4 wires (Black, white, brown and blue) coming out of the power supply (connecting to the power switch) instead of just two wires. I have no idea. Any ideas?

Thanks

This is a standard dual polarity switch found on most old AT computers. This is done to enable both Positve and Neutral to be disconected with one switch.

Thanks, that's what I was looking for!
