Topre short-throw travel

Has anyone ever come across a specification for Topre short-throw giving the switch travel?

This Topre brchure says 3.0mm.

3.0mm, the threshold at which I find mechanical switches to feel too shallow. 3.5mm with Alps is my favorite, and 4mm is quite nice too. I have, however, always liked scissor switches in older laptops, so perhaps these would be okay enough for me, though I have no interest in buying one of these.

Cheers, I'll add that to the wiki. (I can't read any of it, but I can see where the travel is given.)

Why the PDF isn't actual text that you can copy and paste, I have no idea — I'll transcribe and translate the title, but it would be too time consuming to transcribe and translate all of it. (Some of the characters are possibly too crushed to even reproduce in Google's handwriting recognition anyway.)

The PDF doesn't contain text because it's a scan of the brochure, not the original.

Right, so where do you imagine the brochure came from?

I suppose it could have come from Topre directly, but even if that's the case it doesn't mean they still have the original document.

Topre should have converted the original file to PDF. At the very least, scan it with sufficient resolution that this is not the result:

Unfortunately within the keyboard community, there is very little involvement with sources in languages other than English.
