Ok but there is a problem

It's good, I installed it and it works. Remember that all components except the switch are labeled + and -. For all components with this marking, the positive terminal is the gold terminal and the common (negative terminal) is the silver terminal. If the switch is not marked, it is upside down. The two switchable positive terminals are silver and the common is gold. Also, the schematic here on Revain shows that +12V and -12V are applied to the switch, which is incorrect. Where it reads -12 volts it should read as ground/common instead. I look forward to having this available in my trailer on my next trip. I can see my battery voltage and charge USB devices using the battery and solar power connected to my trailer.

Pros
