Air conditioner high pressure switch.
 

Gooday I have a 1996 xj6 x300 soverien and have decided to have a go at re- gasing the air con myself now we have Hychill minus 30 on the market.
I have vacuumed the system and found the high pressure switch has a leak internally.
I need to replace it but am not willing to fork out $100 AU dollars for a replacement.
I have noticed that different models range drastically in price.
My question is I suppose are you able to retro fit a cheaper generic unit into this model given it only operates on given perimeters.
Has anyone done this?
Looking forward to any view points on this.
P.S. my wife calls me the Bodgy Wog.

Shaunn,
Did you try changing the o-ring and reseating?

My switch has failed electrically so I ended buying a secondhand one from eBay for about $50USD. I haven't installed and tested it yet......
