On the switch issue it's more a question of longevity and reliability , an aviation switch like Klixon or HP can be $250 to $1,000 , many using gold plated connectors and they're usually good for 20 years of service.
This could have been a quick temporary AOG fix while waiting for proper switches to be sent out.
If you look at the panel the switches are installed in it's a plain steel plate in contrast to the backlit panels used for the other modules , I think this is a temporary installation done by the factory for some reason.
