I believe all Initiate tier sabers (whether Apprentice or Elite class) do have the holes drilled for the switch, just with a dummy switch installed (or included) instead of a working one.
Almost all hilts, whether elite/apprentice or initiate tier and up, come with two holes for a recharge port and a on/off switch. Champions/Heroes come with a recharge port and an on/off switch in those two holes. Warriors have a working on/off and typically have a dummy switch in the second hole. Initiates come with those two holes covered by dummy switches that can be removed and replaced with a working switch and recharge port. All hilts come predrilled for blade and LED retention screws and come with the screws as well as blade plugs.
