But what it said is that the 'system' won't operate if the pressure doesn't CLOSE that switch. So it's like a minimum pressure sensing device. If you're low on oil, the jacks won't operate...or something.
so if the switch fails completely, you can stick 1/4 - 26 NPT plug in there and jumper the wire to ground, to have emg use of the system without fluid loss
cole parmer 25lb N.O. pressure switch
Or just jump the switch
