Keychron Silent Switch

I prefer tactiles, and I both prefer and require silent switches due to my job duties (I am on video conferences every day, and I constantly type throughout them... this is not just a matter of annoying co-workers). These are the most silent switches I've used, and they are silky smooth as well with very little wobble. Shockingly, the tactility is also superb.

I have 4 keyboards outfitted with Gazzew Boba U4 (and the earlier variants) which are expensive boutique switches. With shipping they end up costing close to $1 per switch. Their tactility is excellent, and they are smooth enough for me, but they are not completely silent. Some call it 'ping' but I don't really like that term. It doesn't sound like the spring to me, but rather the leaf.

These Keychron Silent Switches (no pretentious name) have just become my favorite. They are smoother and quieter than the Bobas, but the weight tactility is almost identical as the 65 or 68g U4. I don't know what else to say about them. They are exactly the switch I've been looking for. As quiet as a membrane switch, but with the feel of a high-end boutique tactile.

To top it off, they are about 1/3 the price of the Bobas. I actually removed all of the Bobas on my main Q6 and replaced them with these, and so far I prefer it. I don't know about longevity, but if my opinion changes I'll come back here and report on it. I wear out PBT keycaps (at least aesthetically) so if the switches have longevity problems, I'll find out.

I almost hate to say those things, because the Gazzew switches are really great and the fellow is very pleasant and has improved the mech keys community, but these cheap switches are the bomb.

There is another review here that gives 1 star, saying the stems are loose and key caps fall off. I don't find that to be the case AT ALL. In fact my Bobas are loose with most key caps, and these switches hold tight to my mt3 /dev/tty BPT caps, my OSA caps, and my KSA caps. I don't know if it was a batch issue or the caps the other person was using, but these stems are NOT loose on any of the caps I've tried them on.

確かに "Smooth And Ultra-Quiet" です！
ですが、キーキャップがしっかりハマらず、簡単に外れてしまう。
ほとんどキーキャップの自重でスイッチの上に乗っかってるだけってレベル。
キムワイプ等、詰め物をかましてキーキャップをはめないと安心してタイピングできません。
めんどくさいのでお蔵入りにしておきます。
（設計ミスなんですかね？）
