Thanks for the reply's.
Yes it is meant to be a plug in switch but some one had cut the plastic male body off the switch and used 2 female bullets to connect it, these keep falling off so I will source a new switch and correct plug to suit.
I do wear glasses, Ha Ha, and laying alongside the car, partly jacked up to access the switch, the 2 exposed posts looked threaded but they are actually serrations along the length of the posts.
Ah well, I've learnt something and you guys have had a laugh at my expense.
All is good in the world.
Thanks
