Anyone have a p/n for this hydraulic pressure switch...

What is the function of the switch?
High pressure cut off
Low pressure alarm
Assuming your jacks are down and the slides out
How long are you staying in place
Remove the switch, goto the hardware store, get a plug the correct thread
Now you know the thread possibly 3/8 pipe thread
You can search industrial farm equipment hydraulics for a replacement switch
Most likely the place I bought my replacement coils from, has a switch
