Title: What makes a Topre more quiet?
Post by: digitalleftovers on Fri, 25 March 2011, 13:43:25

What does "silent" or "low noise" mean in terms of a topre mechanism? (91Ubk-S) Is it a lighter switch? Dampened?  I'm not sure, and I didn't see where it was discussed in the wiki. Thanks!

I think the foam ring dampens the rebound of the switch, but as a result of this mod the switch actuates earlier.

The foam rings are factory installed?

Yep, the foam rings are factory installed on the silent models.

ScarFace made a good review (http://cafe.naver.com/sfkey.cafe?iframe_url=/ArticleRead.nhn%3Farticleid=396) on that.

There is a whole topic (http://geekhack.org/showthread.php?t=9056) on the low-noise Realforce.

That is exactly what I was looking for.  Thank you.

Next time, for the ultra silent, they should remove the spring.
