The Keychron Mechanical Switch series, Keychron did a great job naming and marketing these haha. These are one of the switches I've been looking at for a little while but never got around to buying because they weren't on Keychron's Taobao store, and their main website has the worlds worst shipping prices. Keychron Brown is a brown tactile switch from Huano.
