Nine Phillips screws bite the dust and the plastic antenna frame doesn't budge. But a secret tenth screw behind a liquid damage indicator grants access.

Under the plastic midframe, we get up-close and personal with that oversized slider mechanism.

The slider button moves a hefty metal plunger, which flips a mechanical switch soldered to the motherboard. The X-ray image provides an even better view.

Why the seemingly overwrought design? Is it something to do with ingress protection? Or maybe it gives the switch better tactile feedback? Share your best guesses in the comments.
