The switch on mine is Silent Pink.

I recommend linear light switches, 35g to 45 activation force.

I recommend the Kailh BOX Switch . They are more smooth than the Cherry MX Switches.

Further, if you are used to the gamer's super light Cherry MX Red linear switches, i recommend the Silent Pink switch. It is the Kailh BOX Silent Pink Switch. It is super smooth, and super quiet. Quieter than Cherry MX Red Silent. 〔see Keyboard Key Switch Loudness Comparison

Keycap and Key Labels

The keycap used is PBT plastic, one of the best, with double-shot labeling tech, so key labels never wear-off.

Backlight (functional coloring)

The keyboard has backlight, and the color of the light depends on the function of the key.

And when a modifier key is pressed, other active keys are colored red (for keymap change) or blue (for key macros). If you have remapped keys, the light color changes accordingly.

This functional light coloring system is a superb design, and is also a innovation by UHK.
