How its switch registers
Redragon K645 ships with Outemu Blue, rated clicky by this database. The same bump, but a loose jacket snaps against the housing as the leaf moves. A sharp, audible click on the way down. Loud for shared rooms and open mics.
Drawn distances are the norm for this switch family, not a measurement of this keyboard. The animation is the same diagram the app uses.
Sound
On the sound model used across this site it reads as clacky · crispy · rattly. That is a character derived from its mount, case weight, switch feel and noise rating — it is not a recording of this keyboard.
