fanbus

[jbaldwinroberts]

i am making a fanbus for my computer and have made a basic diagram,

http://viewmorepics.myspace.com/index.cfm?fuseaction=viewImage&friendID=191971138&albumID=834165&imageID=7545311

the question i have is that, does anyone know how i would put in 2 leds for each fan. one to light up when the fan was recieving 7v and one for when it is recieving 12v, depending on which setting the rotary switch was on. the right hand side of the diagram is for my cold cathodes so you can ignore that bit.

thanks joe

i have already had a look at that but it didnt really help me as it uses 3 way switches and i am using these (http://www.maplin.co.uk/Search.aspx?menuno=12893&MenuName=Rotary%20Switch&FromMenu=y&worldid=-2&doy=16m9)

this switch: 4 pole 3 way: FF76H

i am completely new to electronics so just a basic diagram or any help is what i need. i am expecting to recieve the parts tomorrow so maybe i will just have a play and see what makes the leds light up.

here is my diagram
