Taking pictures of dark objects is hard — I can't do it at the moment with the light available.
You did a really good job there — some great photos. And the YouTube video is the icing on the cake — I've used that for a reference for how the clicker works.

I've added another colour, blue, as your shade of blue definitely seems significantly darker than this pastel version:

prove it, looking at the exposure etc it does seem that they changed the colour, and they've changed pretty much everything else repeatedly)
Do your lock keys also use black switches, or are they some other colour? (like with the neon pink ones on beige boards)
I thought I read somewhere that NMB bought up Hi-Tek Corporation, but the best I've been able to find this time around is that (at some stage) it was a Minebea subsidiary the same as NMB. In which case, the switches aren't NMB, they're plain Hi-Tek switches. I did write to NMB, no response yet. I'll try again in a week or so. The article now credits them to Hi-Tek Corporation until we get some clearer information. I think Hi-Tek are long since gone.
