The one which you mention makes lights work or not when pushed may be a battery disconnect switch? I'm not up on new trailers, so guessing!
But perhaps look at how that switch seems to move. If it is a bat disconnect, it will not move and stay but "bounce back" as it is a momentary switch. If it it the normal switch we see most often, it moves and locks into that position but if momentary, it is only operated while we press it, then returns when released.
This can make it very confusing to understand the oepration if a battery disconnect switch.
A battery disconnect switch can be pushed to make a relay operate. That relay is often a "latching relay" that has a magnetic gizmo to latch the relay where we last moved it, on or off. That allows us to move the relay and it stays where we put it without using battery power full time to keep it there.
We go camping, turn the disconnect "ON" and it stays on without using battery all week! A good thing, but it can come back to confuse us!
If we turn the disconnect off and do some battery work and then we want to put it all back together, the switch does NOTHING if we have the battery out. It has to have battery power to turn on the relay and move it to get power to other things!
If we want to move the disconnect relay, we have to have battery power and THEN press the switch to on or we can chase ourself all over looking for what we did not connect as we put the battery back! We can KNOW we turned it on but it doesn't care!
Look at the switches and "feel" how they are acting? Do they snap into place or bounce back?
