Hi Steve,
have not chatted in a while, if you are trying to remove that neutral switch.. the plastic threaded section is a real pain to get out... mine had 4 small holes in it, and I managed to use a small pin spanner to get it out - and I did break some of the plastic off as well because it had been in there a looooong time.....
I gave it a clean and very carefully after much cleaning of the case thread and the remaining plastic section managed to get it screwed back in and working nicely again..... if it plays up again, next time I think if the part is still available I would buy a new one....
cheers...
