Air con pressure switch.

Can it be bypassed? What's the worst that could happen?

Pressure switch fails every year on my new holland T6.175.

Getting very tiresome to replace each year.

Don't bypass it. Replace it and re-wire it so it doesn't fail.

You can just join the wires but it’s a safety switch after all. Buy two replace it and it most likely won’t fail again if you have a spare. If it keeps going bad there is probably a reason for it. Check the pressures just to make sure. I’ve plenty of ac units and rarely have pressure switch failures.

Presumably the gas will escape when it's unscrewed to replace?

Thats correct.

Its a massive pain.

What replacements are you using? Commonly its the thermostat that dies in these, but I always repalce the lp switch when I'm in there. I don't find they fail annually otherwise.

These pressure switches are usually screwed into a valve which will close when the switch is removed so very little gas will escape. So there will be no issue with any replacment. You do not need to even use NH parts which are over priced go to Air Con parts suppliers as switches are standard AC parts.
