Hello! I love DCS profile and finally get the thick version from WYSE PCE keyboard which is so much hype about (not).
I have found the keycaps and switch tops have contact when it pressed down, even in south position. It gives bad feeling, neutralises silence of silent switches.
And only a switch, the stem of which does not fully enter inside, can help. Long pole Durock POM for example work well.
So, this keycaps are not universal thing! And overall quality not reach Cherry OG (see NJ on last photo).Next, let me try to describe a features of some types of DCS keycaps:
1. So, '84 from some IBM keyboard (DCS lettering inside). It thin, sound hollow and hi-pitch. And to some extent have a "contact" problem too. In lesser.
2. 89. WYSE PCE ANSI. Thick and half-thick caps on one board. Both sound much deeper. Both have contact problem.
3. 93. QUME Q500 terminal keyboard. Thin, without "inner frame". Sounds hollow and hi-pitch. But it not have contact problem - for south and north position. Seems it best old DCS caps for silent switches!
4. New DCS Cream Chease and Green. Looks almost like '84, no contacts. Sounds hollow and hi-pitch. For silent gang ok)
PS: seems modern PC and PBT keycaps made with different molds.
