What is switch on sandisk adapter?

The switch on a SanDisk adapter, particularly those used for microSD cards, typically serves as a write-protection feature. When the switch is in the locked position, it prevents data from being written to or deleted from the microSD card, safeguarding the stored information. Conversely, when the switch is in the unlocked position, users can read from or write to the card freely. This feature is useful for preventing accidental data loss.
