The switches are Kailh PG1350, not Logitech, but sort of tweaked a bit, says Logitech's general product manager in an interview. There are cheaper keyboards with such switches, for example Modecom Volcano Blade (tactile is brown). The keyboard is incredibly wide, I would have preferred the TKL version, but it is only available for the G915 wireless keyboard, which already costs just obscene money.
