Can you achieve the same like O-rings do but then on ALPS switches?

Yes. You replace the sliders with cream-coloured sliders which have dampeners built in. The "cream ALPS" switches are found in Apple Extended Keyboard II and Silicon Graphics' keyboards, among others. With other sliders, these switches feel a lot like black ALPS.
See the ALPS Switches wiki page.

I want to remove the sound of bottoming out, not reducing the clicky sound.

ALPS stems are not completely round, so it could be a problem. however, O-rings are relatively stretchy so it might work. let me test it on my black alps when i get home tonight and i'll report back.

Thanks yo.

good news, it fits! it took out most of the bottom-out noise, but there's still a little bit of noise from the keys when it bounces back up to top resting position (this you can't do anything about).

at first, i thought fitting the o-rings on might be a problem because MX cherries and ALPS are inverses: on cherry MX's, the "+" switch of the board goes inside the stem of the key caps. on ALPS, the stem of the keycaps goes inside the switches on the keyboard. normal O-rings can only fit on the keycap stem, but this doesn't seem to be a problem. although it works, i think getting Orings a little bit larger so it can wrap around the actual switch might be a better option.

**** yea, thanks.

yeah i'll take a couple pics of the o-rings on there, i think pics will do more justice. i'll post back here when it's done an uploaded

ok got a few pics and a video. there are 2 ways to put the O-rings on ALPS switches: around the keycap stem, or around the switches on the keyboard. first pic shows it on the cap stems, which i don't think is ideal. 2nd pic shows it on the alps switch. click on the picture to enlarge it:


it fits pretty loose on the stem, but that shouldn't be a problem


putting it on the switch takes more patience than putting them on cherry MX, because they have to be stretched to go around (it does fit though). it's hard because as you try to put them on, the switches depress as you apply pressure to put the o-rings on. luckily these o-rings are soft enough to stretch this wide, so it's more like an oval. O-ring on key 1 is a normal standard one, key 2 has the larger fat O-ring, and key 3 is without any O-rings


i'm uploading a video of the sound characteristics of this O-ring mod right now, and i'll post it when finished

Is an ID of 9.5mm ok or too big for ALPS? I found these larger o-rings on Amazon (-012):

EDIT: There's also 7.9mm ones (-011) which might be a good fit:

9.5mm ID is most likely too big, the fat ones i have has a OD of 9.5mm, and it looks a tiny big bigger than the switch, so it'll be a loose fit. and a 12.2mm OD on those might not even fit inside the keycap. the ones with 7.9mm ID might be good though.

Nice video, and good sound. I can hear that keyboard ring!

The dampened sliders shouldn't remove the click at all.

I'm sorry, I did not see trax's post before GlaDOS had bumped the thread. False_Dmitry tells the truth. The dampening on the sliders does not impart the click sound at all.

I hade mod'ed my Dell AT101W so that the switches have sliders from "Cream" Alps but tops and "click leafs" from "White" Alps. They are clicky, but the sounds of bottoming down and snapping up are dampened.

On Cherry MX, the tactility/click is in the slider, but on Alps, the tactility/click is in a leaf spring called "tactile leaf" or "click leaf". Even though Alps sliders have different colours, they are all mostly the same shape. For instance, you can put a White slider into a Black switch and it will feel the same.
If you remove the tactile leaf, then the switch becomes linear. Because tactile leafs have different shapes, the top of the switch can also be a different shape, so it is best to swap that too. All switch bottoms are the same, though. Another difference from Cherry MX is that all Alps SKCL/SKCM switches can be opened without removing them from the PCB/plate.
