!!!Advice needed before saturday morning!!!

Hi guys. Im changing the oil cooler/buzzer of doom switch tomorrow morning
Ive just had a poke around and disconnected the wire. Access is a bit sh1te to say the least.
My question is I don't have a socket/spanner large enough for the switch. Seems to be 25 mm accross the flats.
Which tool does the job socket or spanner? I will buy whichever seems the most poular on here because you guys are so knowledgable. (must win some brownie points for that)

Right. I changed the high pressure switch. 22mm long reach socket. unbolted the exhaust cover bolt just below the switch,pulled it back a bit and wedged a hammer shaft to keep it away from the switch area. Easier than I thought with access from the top.
However, the bloddy buzzer & light still come on. Checked the low pressure switch and the terminals are clean.
I can't seem to separate the two pin connection (on top of the engine) which connects the low and high pressure cables
separately. Any advice on this so that I can check these terminals?
It Is a 1.9 petrol waterboxer dg engine. no smoke, really quick of the mark and pulls really well. Just the bod problem
