Yessir, I'm using a CF8.
If you are using the Stock SD card that came with the board I would
recommend making a copy of it so you hav an SD card and config to
experiment with and not loose the original settings.
Then You can try and go in and turn off all that on the fly color mixing stuff
that way you can see if the switch is working properly or not.
Also if a switch has a metal case make sure there isn't any metal contacting
it when activated and that the switch its self is insulated or has something
between it and what it is touching.
I typically will use a rubber bump stop or something similar to have contact
on a metal body switch so it doesn't short out.
