The Penguin switch is a new silent tactile switch from Akko. Its tactility bump comes at 0.4mm after the initial key press and stops at 2.0mm. It bottoms out at 3.3mm. When you compare the new silent switch series with Akko's previous silent switches, you will notice that the Fairy and Penguin switches are "real" silent switches as they barely emit any sound. They are both great options if you are looking for a quiet build.
