How does moving the little switch on the side of an SD card write protect it when accessing it from a computer?

This was also done with floppy disks, music cassettes and VHS cassettes, and they made it work the same way on SD cards as they did on those older media: depending on the position of the switch, it either trips or doesn’t trip a little microswitch inside the card reader, telling the card reader whether it’s allowed to write to the card or not.
