I think the PO had lots of problems with the coach so he installed the Murphy switch to  keep " Murphy " from causing any more unforeseen problems.
It seems to be working so I'll not touch it  ^.^d

As the article states Murphy is a brand name,commonly used in the oilfield on gas compressors and generators that are
unmanned and run for weeks at a time,try and determine what it does and call it by that function,calling it a Murphy switch is like
calling it a Honda or a Ford switch.


I was unable to get the picture to load but "Murphy" is the name brand on the little box under the dash.

Trying to figure out why the previous owner did something is a fun exercise, simple reason being the most likely.  In this case, the PO was probably concerned a sudden loss of oil pressure.  That being said, it's something I'd keep an eye out for but not worry:  Your engine ecm probably takes care of that for you already.  So if your oil pressure gauge goes to zero, but the engine keeps running the engine may still have oil pressure.
