Title: Switch LED connection problems
Post by: peter on April 08, 2009, 11:14:02 AM
HELP HELP HELP

Please could someone help me with this? I thought it would be so great to have an LED indication when a switch/bend will be switched on, that it would be easy to connect. But now after many times trying wiring up all sorts off connections I just don't know what to do any more. I started out with the idea that it'll be easy, but now I think it's impossible...So please help!

I added a drawing explaining my connection situation. Sorry for the misstakes and all, I'm so very new to this.

Use a double pole switch, so you've got one for the LED and one for the circuit you're trying to switch.

And then it becomes so simple...I'm amazed about that the solution is so simple that I just didn't see it.
Thanks so much!!

You can do the same with rotary switches.. You just need 2 poles.. So say you have a double pole 6 throw switch you use 1 pole for power to 6 L.E.D's and 1 pole to 6 bend points..

If you've got a rotary switch you can use a 7-segment display and a bunch of diodes (quite a lot, really) to display a number or other symbol ;-)
