National Air Bag question

There is already a battery disconnect near the steps and I have fan, map lights, generator on/off also. I will try and take a picture and post it here.

If the switch returns to the center position, they are called momemtary switches. They are used for different functions.
It could be for battery disconnects
Or Auxilary start funcrion which ties the coach and chassis batteries together for extra startin.
Could be for the start and stop functions of the genset.
Is there any pictures adjacent to the switches or inside the switch it self?

I have a National Tropical and without looking at the dash I can't tell you what everything is for. I can tell you I don't have any switches that don't control something. A possibility is I have two separate toggle switches that control the auto visors on the passenger and drivers side and a toggle switch for the fans above the windshield. I also have a toggle switch for a reading lamp above the drivers seat. So if your motorhome doesn't have any of those items, that may be what the switches were intended for. They are going to install the switch whether you have the item installed or not. I don't recall any switches labeled as "Aux" so my guess is they are just extra for things you may want to add.
