How to make this switch?

[Hitokiri Batohsai]

I want to make 1 ON/OFF switch that can control both of the above items. The top left, is a Manhattan CCFL which comes with its own sound sensor and switch (which I labeled SWITCH). The yellow and black wires from the molex go to the CCFL
The right is the wires connected to the front casing light of the Thermaltake Tsunami. The red and black wires from the molex goes to the lights
The black rectangle with yellow, black, red are molex.

Anyway I can make just one switch that can control both?
I did once, but I made a switch that turned off the entire PC, in a sense, cutting the voltage to the wires, and the switch is now useless. Now I don't want to repeat the mistake again. So a diagram of what I should do and what I need would help me alot.

I dont quite understand what your asking but i think your trying to control 2 things with one switch?? if so then if the 2 things use diffrent voltages just use a switch with 2 poles like a STDP (Single Throw Double Pole) im not shure if thats what your asking thou maybe some one else could correct me if i misinterpreted it

Sorry, I want one switch to control both 5v and 12v rails at the same time.

You just need a 2-pole switch(DPST). Hook the 5V device to one pole and the 12V device to the other pole and they will switch on and off simultaneously.

you could run a normal switch and just have it befor the 2 titems on thr 12v rail, then use a resistor to bring it down to 5v for the front lights

Almost positive somthing like what i said before would work, such as this:
