Or indeed any keycap chunky enough to accommodate a 2x6mm tritium filled glass cylinder.

crappy pics by me since I didn't have the time to really get good pics.


It's a **** ton of work to do with the caps I did it in.  You have to remember that they may shift in the mold and have to think about how to keep it in place in the mold or make it work with the design.

How well do they light up?  Judging from the conversation on the company's website, I assumed that they would only be bright enough to be visible in a dark room and that the light from the tritium max would not be visible in the glow of a monitor in an otherwise unlit room.  I also wonder how long they could withstand the mechanical stress of typing if they were put in a more commonly used key.

Tritium vials are very resilient.  You'd worry about breaking the PCB before you'd break the cap.

As for brightness, it depends on the size of the vial.  Some are more visible than others, but most require at least a dim room, just like GID powder.

I believe that's what cc used in the sezunite and murica type s. Pure speculation tho.

Based on photos, I always assumed retroreflective beads.

I am not convinced with the type s. But from memory of photos,  the sezunite looks alot more like your photos.
