MacBook Pro turning off when pressure is applied at a specific spot.

Hi, my laptop has been randomly turning off. I noticed that it happens when I apply pressure to the bottom of the laptop and sometimes if I am using the trackpad.

I took the cover off and played around until I traced it down to pressure being applied to this metal bracket on the logic board. There seems to be a metal piece that sticks out underneath the bracket that holds something in place.

Does anyone know why this would happen or what it is for?

thanks!
