Hi,
I'd like to wire an illuminated rocker switch as an "on-off" switch for my AT power supply. The original switch had 4 wires to it, white, blue, brown, black. I had to bypass the old switch by looping the 4 wires in pairs, ergo,. hooked white to blue, then brown to black in order for the power supply to come on. Works fine that way, I just have to plug & unplug every time I want to use it. I now have an illuminated rocker switch that I'd like to hook up, I'm a bit confused as to how to do this, this new switch has 3 tangs or spads on it, can you tell me how to wire this to the previously mentioned 4 wires that are are tied together as white/blue & brown/black :confused:
Thanks,
Tim
Here's the switch I have SPST Lighted Rocker Switch - RadioShack.com

Nope, because to replace the original switch as originally designed, a DPST switch (rated for at least 10 amps @ 125V AC) is needed instead of a SPST switch. Searching Radio Shack's website did not turn up an illuminated DPST. Check with an electronics supplier such as Digikey or Jameco. Or, do a Google search for an illuminated DPST switch as there are some nice looking switches out there.

Also see AT Power Switch.

The Computer Power switch interrupts the Neutral, Needlessly, I feel.
I would tie these 2(blue and white) together and a white pigtail from there(this will be the switches neutral),
Then connect Brown to the line side, and the black to the load side.

Thanks for the replies, still a tad confused, but then again electrical endeavors aren't really my forte'

Ahhh terminology:

Your computer comes with a universal power cord with probably a universal power supply. Meaning, it operates from about 85 to 285 volts AC. In the US we use a 240 system that is really two 120 VAC supplies 180 degrees out phase. When they add, we obtain 240 VAC. That means that in order to remove power you have to cut power on both of the 120 legs.

Thus you can permanently connect the blue and white wires.

Connecting the blue and white with a switch will turn and off the computer.

You have to determine which side is LINE and LOAD. LINE is the color that goes to the wall. LOAD goes to the power supply.

Determine those colors and we are set.

Scleros link shows the colors and the connections for the switch, I would not switch the blue and white(neutral), I would switch the brown and black(the line or hots).
Tie the blue and white together. Neutrals can stay together.

Great! Thanks you guy's. I appreciate it greatly!
