I bought a SanDisk 32GB Micro SDHC card for my Android phone a while back. It came with a Micro SDHC to SD adapter, and the adapter has an unmarked switch in the same style and location of the write-protect switches on my other SD cards.
It is not a switch. It is a lock. Its physical position is sensed by a switch inside the card reader, just like the lock on floppy disks was sensed by a switch inside the floppy disk drive.
