Its a locking nut for the big nut but someone got their measurements wrong in the whole set up and have shortened the adjustment distance. It might be better to just move the tab between nut 2 and 3 and then it will still be lockable. I'm still thinking about this and may just end up bending the tab ? I don't really want to keep messing with this as it may take several attempts and I'd sooner be riding

Looks as if the left nut is part of the u shaped connector, the middle is the locknut for same and the right hand one is for switch adjustment timing.
Also from the placement of the rivets it looks like the switch is a " microswitch " and has limited travel hence the separate adjustment nut against the tab.
Could be to remove it and replace it with some washers or plastic hose to get the switch to operate at the right time or get what's called a "half nut" which is half the with of a standard one?
The left nut is free to move and acts as a locking nut for the U shaped connector which has a punched threaded hole. So there would be a gap between nut 1 and 2 if the pedal was higher.
Yes washers or half nut is another option thanks. Being a micro switch there is not much leyway in the spacing. I would like to leave 3 nuts in place incase the next owner wants to higher the pedal.

The air gap/clearance between the said parts must be within the factory specs and usually is of up to a few millimetres or you have to have a free play of the brake pedal/lever.
