It still is very confusing. Photo is not 100% accurate.
OK I just read the sales page. Sounds like they removed the alternate switch and parts used to trigger it. Maybe just put a wired jumper where it was.
That would also be why there is no On Off button as Tuicemen indicated. Not wanting to waste front covers with the hole in it for the button. Cover it with an X10 sticker.
Why no ground pin. Cases have two pins and so does the outlet. Not wanting to waste parts. Keep it two pins.
Less parts. Less cost. Raise prices.
So the buyer again should read the exact descriptions of what it does and you get. X10 makes changes and not a word from them on what they did.
