power switch

I have a 2020 Kodiak Dutchmen 201QB. I have a power switch above my bed that appears to do nothing. Hoping someone here might know what it is for... When lying in my bed I am staring at it when going to sleep, it is directly above my face, above my bed. There are cupboards above it, for clothing.

By adding this switch I am able to completely shut down the Jensen audio unit to prevent it from being in standby mode and using power while boondocking.
