Called an elastomeric connector.
BTW the "black plastic dome" is actually a chip bonded to the PCB and wired by fine connections. The plastic is a protective cover. Called "chip on board"

Thanks for an excellent answer!

On a separate note, I've just found a fix for a broken sliding wardrobe door roller which was proving to be a real PITB. The nylon roller was fixed to the supporting bracket by a metal rod running through its centre. This had worked loose over time and would have required welding to repair (which I can't do). After studying it a while I managed to find a bolt of similar diameter and managed to tap a suitable thread into the hole in the bracket then screw the bolt into place nice and tight. Job done! (well apart from having to put all the wooden trim I had to remove back in place and make good... lol).
