, but doesnt switch.

I have just removed the new switch - the nut was round right up to the head. the switch was wound right down into the box and not working, but having checked the switch again it works fine out of the car.
I am beginning to think it must be the mechanism, but the front arm moves over to, what i believe is far enough.

doesnt sound like selector is even if linkage appears to be, as switch works directly off the selector ,jack a wheel up and try

if its not worn plastic pivot bushes it is adjusted by winding pivot in/out,you could try with a spanner on the nut ,its possible that spigot has jumped out of shaft slot too

oh yes
to be precise - the new one does - the old one didnt, which is why i just thought it was the switch, but apparently not

17 on mine - came from a spare T-box, so i am confident that the switch is the correct one & OK. PRC2911

Can you try feeding a suitable sized bar down the T/box to measure how far the switch needs to be in to contact the diff lock fork then compare it to your switch? See this for how it works https://www.youtube.com/watch?v=TH4r71evEfo

To check the gearbox movement, you might remove the switch and put a long screwdriver vertically down t'hole. Then when you move the lever into the diff locked position, you should feel the cam try to push the screwdriver upwards. (as per Kwackermans post)

undo top nut/bolt , remove pivot clip ,slide out lever , 13mm spanner slacken lock nut ,wind pivot out a turn or 2 refit linkage and try ,nip top nut/bolt reasonably tight to reduce any slack, presumably its not going into diff lock with lever but will with a spanner
