I believe Framework has their webcam LED setup like this. At a minimum the physical switch cuts power to the whole webcam assembly.
And the Framework Laptop also has a switch for the mic. So even the mic can be completely turned of on the hardware level.
That is exactly how the webcam light is setup in a Framework. The light is wired up to the camera sensors power, so whenever the camera has power, so does the light. The switch also fully disconnects it from the computer itself. At least in Linux, you can verify it using
lsusb. You can see the camera indicated asRealtek Semiconductor Corp. Laptop Camera. Whenever the switch is flipped though, it disappears all together from the list.
