blue switch - very clicky/nice (a little loud). the keyboard has 68 keys and a blue backlight (NOT RGB), it can be animated it different ways using its software. The keyboard has absolutely no faults, it works perfectly. Only reason I am giving away is I needed a bigger one. The only thing is, it's a bit dusty, so you might have to remove the key caps and wipe off the dust. It works with Bluetooth or with a USB C cable. Charging lasts pretty long (around 1-2 weeks).
