Replacement Use/Store switch

I have a 2017 Four Winds 28z E450.
I am wanting to replace the battery Use/Store switch with a Carling switch as I am adding a few other switches, but the issue is I can't tell what type of switch it is.
It feels like a momentary DPDT switch, but I don't know if it is reversing the polarity or not.
It appears to be controlling a latching relay.
Anyone have to deal with this switch yet?

Your suppositions are correct and it does reverse polarity to the latching relay control coil.
