Wiring a switch to LEDs?

post #1 of 21
Thread Starter 
Hi!


I was wondering how I would be able to wire a switch to some LEDs?

I'm going to buy to pre-wired LEDs which each require a 4-pin MOLEX cable for power (from the PSU).

Now, these to LEDs I wish to hook up to a switch which has three "legs" Power, ACC and Ground.

If someone could draw me a diagram or explain to me, how I would do so, that would be great!

Also, the pre-wired LEDs already have resistors



Thanks in advance!

And by the way I was going to use these LEDs (2x):

And this switch:

I'm putting these 3 mm LEDs in the front panel of a NZXT Tempest EVO case

Just switch the negative side and you're fine. DC FTW

How do you mean?

Could you draw your point in paint for example?

It's just preference, you could switch either side, but I tend to do my low-load switching on the negative (black).

The guy above me is right. I like using positive though so that any time I need to do maintenance I know that the wire with the switch is always positive.

Have you considered something like this?

And lemans81, thanks for the input, but I cannot find a pre-wired switch like that on www.aquatuning.de

Question, do the LEDs come with resistors or are they meant to otherwise run in series on 12v like that?

They already come with resistors - or at least I think so It's these:
