Quoted from Bach:Should it be touching the plate switch (circled). When it’s not touching the lights come on.
Yes, it should. Is the top circled sw. making contact? It should not. The sw. should go, from the bottom, open, open, closed, open. One hint is the number of spacers: if you look at the oddly shaped circle area you'll see there are two spacers for NO and only one for NC.
The upper pic in post 16 is Tilt? The long blade with the lifter needs to be bent down to touch the plate and the contacts need to be making solid contact. The lifter should open the contact when the plate is pulled in.
