There are not really many information at thewiki, so I dont know the switch type before I got it.
I cleaned the keyboard today and made some Pictures.
It has blue KPT-like switches(clicky), except the spacebar switch (white KPT-like switch/heavier to press, also clicky).
They feel after I cleaned and lubed them nearly the same like real blue KPT switches (I own a KPT-84 keyboard).
Here are some pictures, from the keyboard and the cleaning process:
