Can't seem to find much discussion on them. You can see them in the picture here, they're just to the right of the square portion of the retention bracket. Kinda brownish-looking with 2 little white blots. Those are the switches. The whole thing has a little piece of protective film over it, that's why it looks brown. Presumably it's there to keep the switches from getting flipped by accident. Looks like another miscellaneous piece of electronics untill you look at it more closely.
Any ideas?
