how exactly does the camera shutter key work physically

[Eastbei]

how does the camera shutter function. Is it software, Is it hardware, is there  an electric charge that occludes like smart glass, If I take it apart will it still function. Can I disassociate the camera from the microphone or the indicator? so have the camera obscured while the indicator led is off? basically want an engineering breakdown of how this privacy feature works.

Really? Crickets. This community sucks if there is no access to the engineers that can actually tell us how this privacy feature is enabled. There should be charts and diagrams explaining how are privacy is being handled.
