Which switches come pre-installed in the Skoll?

Hello,
I was wondering which switch comes pre-installed with the Skoll.
Your website says : Buttons: TTC Golden Switches – https://fr.x-raypad.com/product/g-wolves-skoll-gaming-mouse-rgb-lighting/
But G-Wolves says: Main Switch: Omron D2FC-F-K(50M) – http://www.gm-wolves.com/SK-L3360
I know there are additional switches that come in the box and those appear to the the TTC Golden, but which are pre-installed? Thanks!
