Kailh Heavy Blue Key Switch
Ancient Grey,which means long-standing and well-established.,The most notable of the quartet is the linear Ancient Grey switch that requires a hearty 95gf (+/-10gf) to actuate.
The closest thing Kaihua has to that is the Box Navy, which does have 95gf (+/-15gf) at the tactile bump, but it’s not linear like the Ancient Grey switch. That puts the Ancient Grey in rarefied air.
actuation points of 1.8mm and total travel of 3.6mm
