Making a switch

I want to make a switch for my LED's on the front of my case. I bought a dual cold cathode light kit, and it has a switch for it. Here's a VERY simple drawing of what I'm talking about :

What I want to do (if possible) is disconnect where I circled in red, cut off the end connector, and "splice" the wire into my LED's wire. If I know what I'm talking about :rolleyes: then the power will go from the PSU to the dongle above, then to switch (which can be on/off), then to whatever is connected to the switch (being my LEDs). Could anyone tell me if this is right, how to do this, give me a link on how to do this, offer other ways of doing this, etc.... Thanks in advance.
 
I don't see why it wouldn't work, but I'm not sure I get what you are trying to do.
Are you trying to make the swtich for your cathode lights also be the switch for your LEDs? If so, I did something similar a while back and it works fine.
 
Well, I have the Aspire X-Dreamer II case, and it has 6 LEDs on the from. I just would like to be able to turn them on/off because they are cool but also very bright... plus this would just be cool to me to do something like this. Here, I have nothing better to do so I'll put up a picture :

Also, you said you did something like this a while back, I imagine you cut the wire, put them back together yourself... could you tell me how you did this, or a link to where you got your information on how to do this (assuming you got it from a link).

I was checking out the wiring from my LED's and they are on two wires... Here's a picture :

So here is what I think I would have to do now. Disconnect here:

This would give me two seperate lines to make it even, but now I dont know what happens when the power passes through the "box" between these wires, and I don't know if this would change the volts or whatever.... Sorry I don't know anything about electricity... Any help would be great thanks.
 
You don't know what the little black boxes are you're trying to by pass, or you want to remove the connectors and make it a solid wire. If that's what you're talking about, you can get some tiny wire and solder the amount you need in that gap.
 
Yes I want to make a solid wire, for all 4 wires (2 on each since the 6 LED's are split into 2 wires, 3 lights on each). Would i matter how I go about connecting the wires, blue to white, white to white, ect... or is all that just for looks? Also do you know of a link where i could go to learn how to make a solid wire out of two?
 
OK, first off. The colors do matter. One color represents (+) and the other (-). You can simply cut the little black box off and solder the two wires together, but you may want to look up some tutorials on soldering if you're not used to electronics. or you can simply twist the ends of wire together and secure it with electrical tape. The choice is up to you

yeah but since he is just putting a switch in series then it will not matter if he attaches it on the -ve or +ve line, the led wireing setting does matter, but then the case manufac willhave done that for him :D

Just stick the switch on any of the wires black or red it will work the same
 
Well I'm in luck because my mom and uncle own their own business where they make the electonic part of engines to cars and whatnot, so I'm sure they will have the tools and could probly show me how to do this... But coming off the LED's, I hav one white, one blue wire..... and coming off the switch I either have two white.... or one red, one black... You wouldn't happen to know all the (+) (-) colors would you? Or how to find out?.... Thank you for the help so far.
 
Alright well, I spliced all the wires, turned the copmuter on, turned the switch on and all seems well for about one second then the bottom two lights go out and the top one turns orange (fire) and blows up. LOL. So now I don't have LED's but thats fine, it was a learning experience and I got a good laugh out of it... Now my question is, why did it do this, and how do I prevent it from happening next time? Before cutting any wires, I noticed 300 watts written on the LEDs cables.... would this matter at all? And just to show exactly what I did.... here's one more picture (sorry for all the pictures) :

I still have the other 3 lights on the other side, and would definatly buy another 2 dollar switch if someone could help me out here and tell me what to do...
 
there is 1 thing.. you can put the ground of the lights constant on ground. that way, you would only have to swich the 12V. (makes it more reliable, an its les work :) )
