Lot of UV’n there M, nice work getting the details ironed out. Reminds me of when we used to paint posters with black light paints and fill the room with the blue glow… late 60’s… geesh, wasn’t that just yesterday?
What are going to use some much UV radiation for?
Seems a bit dangerous :).

That is a really good colour, Don! I may go for that in mine too!
Now I’m waiting for three Nichia 319AT’s to arrive.
Really nice. I don’t know if I’d dare try it myself though.
Sorry for late answer. It is pretty good. It has a little burr on some parts and the glass breaker is formed from same material az that piece of the chain so it is not a separate pressed in part. It has Leatherman logos and brand mark 
I mostly use it as a jewel and not a tool. But I hasn’t seen an original one so I can not really judge differences
Not a mod, only a fix:
The switch of my beloved RGBW Color Emisar D4 got broken, and since I wasn’t patient enough to wait for replacement parts I fixed it quick and dirty. You see the broken switch at the right in the left picture. The dome came off (the scratches in the plastic base were caused by the tweezers when removing with hot air). The new switch at the left (the smallest one I had) was still too large for the tiny 6 x 6 mm board, so I bent the legs down and soldered it to the board with hot air (right picture). The rubber boot had a bump in the middle which I had to cut. It’s still more protruding than before but it works at least.
That’s what happened to mine, I just taped the dome back in place, still working so far.
Nice fix though :+1:
That’s what I tried first, but although it worked, it didn’t feel right when pressing. Used capton tape, didn’t have anything better. What tape did you use?
Fairly sure it was kapton tape I used too. Still would like a source for these switches though.
Are they anything like these?: Page Not Found - Aliexpress.com
Edit: or better this one: Page Not Found - Aliexpress.com
Close, could be compatible, the Emisar versions are on like a little fibreglass board with the connection pads on the underside.
I also looked for this switches and found some, similar to djozzs first link. Asked for exact metrics and learned they were too big. In fact 4.5 x 4.5 + length of the connectors instead of 4 x 4. The second link is interesting though.
Problem is the small board of 6x6mm, longer legs would touch the casing.
This is the original D4 switch (without dome), 4.5 x 4.5 x 0.6 mm (height approx. incl. dome):
(Got a cheap macro lens for my smartphone)
Height without dome is 0.4 mm, so I think giorgoskok found the right one. Thanks!
Updated previous post with a 30pcs link ,if it’s the correct switch of course :+1:

Height is claimed different, but I guess it’s just a typo.
