Nice switches. I use the same (without the safetycap) as fuel cut off switches. When there is an engine fire, the led wil lit so that I see in a split second which engine to shut down.

You just need to select an interface (there are lots of possibilities).  You can assign every function from fs to these switches that you want (even have the fsweather change if you like).
