I just found this project for an A/B/Y Switcher, but I noticed that for the version with LED's, it seems the current limiting resistor is going to the wrong leg of the LED, and that a full 9v would be hitting it.

Is it the case that having the resistor on the other side of the LED would limit the current and stop the led burning out too?

If anyone know of a passive A/B/Y selectotr project other than this one, feel free to let me know

Thanks

... it doesn't matter which side of the LED you put the resistor.
