There is no big difference between switches, this one with 3 positions are better choice for me, cause that one with 2 positions with it i can't turn off everithing, with mines one i can, so it's better then 2nd one..i made a new one picture with right wired LEDs..
I solved the problem, here you go my final shematics..
1,2 and 3 are positions of the switch, when is on 1st LEDs blink when music, on 2nd is everithing off and on 3rd LEDs are always turned on.. :)
okey, thank you for your help I appreciate it..i will make it so we will see what will be :) thx again ;)

just a one small question pls, when is switch in the 2nd position when LEDs needs to be turned on allways...
i think that it didn't burn cause power suply from computer on 12V rail has maximum 18A, but that current is maximum which can power suply produce, so when i attached diodes i think that from 12V to the LEDs goes amount of current just needed by LEDs, nothing more. I saw on my headphones that...
and i think that, but now my only problem is what resistor to put on base of transistor? i can start making this circuit already, just a value i need..
okey, i tried and made one without resistor and they worked very good..i used shematics which i posted in my 1st post..but now i want to make with 2nd shematics which i posted, i will put this one of 680ohm and then it will have 8mA so we will see..and on transistor i will put some maybe of...
it's attached to the computer power suply and on computer's motherboard for sound..so can you tell me pls which resistor to put near transistor and with LEDs cause they are BLUE bright but they can work on maximum 10mA..?
okey so tell me where and whick resistor I need to put..? I bought one of 680ohm for limiting current on 2 LEDs, but where to attach it, near power suply or between LEDs and switch?
i found one schematic for my problem here..
i'm using LEDs with my computer and they are attached to the PC power suply..
i want to know will i need some resistors maybe?
I want to make this circuit if posible with one TIP31C transistor, sound banana and 2 LED's and i want when is music turned on LED's to blink, but when not music LED's to be still turned on (cause i made it to blink but when there isn't music LED's are turned off)..and tnx in advice
