Little switches on the Mobo

Hi to all,

While upgrading my Ram from 4 to 8 GB on my MacBook Pro Early 2011, I noticed some small switches when the Back Cover removed.

I found an image on the internet and I have put a blue cycle on these little switches.

Any clue what are they? I thought they might be for intrusion alert when open the Cover but no, the Mac Power's up even with the cover removed.

thank you guys, nice to meet you.

Those are not switches, these are for grounding the backplate, that's all.

Ahh, I see, thank you very much.

By pressing them them down they were recovering again to the starting position so my thought.

This is to make sure they make perfect contact with the backplate, they also need to move a bit for when you press on the bottom so you don't get dents.

And there are plenty more of them on the Logic Board.

Yes thery are plenty of them I just realised by looking again in the image.

There is a whole row of them in the right hand side. However in my Board they are silver and not gold as in the image above.
