I might be stupid, but why would you want to protect your pressure switch? From what?

Just read on Peter's forum that this design takes the amp load away from the pressure switch and uses the relay to handle the load instead. The switch only takes enough power to run the relay.
Seems like a lot of hassle to me,.. easier to replace the pressure switch!

Yes if you like spending money and replacing pressure switches. The relay is much more heavy duty, and dosn't need replaced very often. There is also the chance of loosing one or the little bits inside, or stripping the threads, with constantly unscrewing and tightening the screws.
