Either way, I'm not convinced that the tactile element in a Topre switch is going to magically explode 1/3 of the way through the useful life of the keyboard.
hey i'm just quoting what appear to be specs, and I'd welcome additional official information if anyone has it...
but how long topres last is kind of a side discussion here... I think the speculation began here regarding keytronics claim of 20 to 30 million for domes (which they do warranty anyway, regardless of whether they actually last that long). I dont know if keytronics can literally last that long, but i'm saying it wouldnt surprise me if they did last at least 10 million, first of all. Second, to me thats a pretty long lasting board since I estimate that to mean decades of use, and
most people are more likely to spill coke on it, or simply get bored of it, well before it actually physically wears through.
So on the one hand is the discussion about technically when does it wear out. Seems we dont have enough specific info, either about the chemistry of modern-day rubber compounds, or even the internal construction of the keytronics switch. But probably a case can be made that higher end dome boards today can plausibly last 10 million at least.
On the other hand is an implied discussion about 'how long is enough anyway?'. The latter question of course is subjective, but a case could be made that 10 million = 40 years or more = long enough for vast majority of people, overkill even.
And even if it did wear out - the third option - technically its under warranty anyway and you can pursue that channel if you choose, too.
In other words, longevity with keytronics (and by extension perhaps to most higher end dome boards), should be, for most folks, probably a non issue. Especially if its warrantied for 30 mill anyway. You dont have to believe the specs literally.
