I'm in the middle of the same problem. On mine I was only getting 7V at the compressor so it wouldn't kick in the clutch. I looked around and was able to find switches small enough to fit at local AC shops but the capillary probe would need to be bent at a 90 degree angle risking breaking or kinking the tube.

So i took the old switch and there is plastic panel on the side that is removable through which you can access the contacts. I cleaned it up with electrical contact cleaner and small file and on the meter it tested OK I could get 12V through it. At least on the bench. I haven't put it back in yet to give it the real test yet though.

You might want to give it a try.
