The heart of any mechanical keyboard. These mechanical switches are manufactured and produced by Kaihua, and are fully compatible with our GMMK & GMMK PRO. Kaihua is the first company to truly innovate over the original Cherry switches, which have traditionally dominated the market. The Kailh switches are unique and come in many varieties, differentiating itself from Gateron and Cherry switches. The Kailh switches come in three types: Box, Speed, and Pro. Pro switches are the best of both worlds between Box and Speed switches. They have a shorter travel/activation distance than box switches but a greater distance than speed switches.
