Ducky comes with a Kailh Midnight Pro Silent switch kit of 110 switches, perfect for you who are going to build a custom keyboard or want to change your current switches. The Midnight Pro Silent is an improved version of Kailh’s previous Midnight Silent. Kailh has brand new noise-dampening pads that should be thicker and on both sides at the base of the switch. Which enables a quieter and more stable typing experience.
