I am using the way Ivlark shows for 3pdt wiring and I am pleased by it. Wiring the led by itself causes a lot of trouble as it is, so I thought maybe I would do it like this and make my life a tiny bit easier.
Instead of the old way (left) I tried the right image. At first I had some second thoughts about what would happen when the switch is in "down" (off) position but decided since it is ground and not hot it wouldn't cause any trouble. Made a timmy that way and it seems to be ok! Do you think it can cause troubles to other builds?
Just thought I should share
