Yesterday I received some new low profile switches from Kaihua.
They are clearly inspired by Cherry ML, but they are not compatible with them, the stem is very close but the keycaps don't quite fit. I'm told that they are testing these switches for over an year now and they are finally releasing them.
There are three versions:
The brown one is the closest to cherry ml but definitely smoother. The red is really nice, I don't have specs yet but it's definitely stiffer than cherry mx red. The clicky one is the big surprise, imho. It feels really good, it's a little like a futaba clicky, but heavier.
I'd say they are all very well weighted, but slightly on the stiff side. If you like very light switches these are not for you.
They are all clear top, backlight compatible and of course PCB mounted (no plate). The travel is approx 2.6mm.
All in all I'm really enjoying them and looking forward to build a keyboard out of them. Unfortunately we will have to wait for the keycaps to be able to actually use these little guys. I'm not sure what's kaihua's plan here. OEM gaming laptop? Wireless keyboards? We'll see.
I'll try to post more pictures soon.
