They appear to have the same electrical ratings according to
this and if the original S2 switch is a -67 they should be the same physically as well.
[Edit: In an earlier edit I said the P2 had a lower electrical rating than the S2 based on what I read in the
full catalog, but I misread - it's actually saying the P2 has a higher rating than the S2.]
The other main difference I see is that the S2 is a momentary-on switch (meaning it returns to the center OFF position as soon as you let go) but the P2 is not momentary-on (so it stays turned on after you release the switch - you have to manually return it to the OFF position). Whether that's a problem depends on what it's being used for & what the consequences would be if it's left in the ON position for a long period of time (something that's unlikely with a momentary-on switch since it's only on as long as your finger lasts). The 2010 Roadtrek 190 manual I found online didn't go into enough detail on how the battery switch was used & how it was connected for me to have an opinion on that. And it's not just deliberate activations you need to be concerned with - what if you accidentally bump the switch on your way out of the van & it stays on all day? Or it's the end of a trip and winds up staying on for weeks, until you use the RV again?
The difference between the dash numbers seems to be the size & shape of the terminals, so I'd take a close look at the S2 & try to figure out exactly which one you have & if it matches up with the P2-61 shown in that document.
Not sure what the "C" is for or if it's important. I'm also assuming here that when you say "2S" you mean "S2" - if that isn't the case then ignore all of this, but I don't see a "2S" in the full catalog.
