Thank you for this. I have a card that mysteriously got locked and I could not use. Now I know how to unlock it. I was unaware of the little switch on the side.
See, someone benefited from this whole shebang!

Did you ever wonder what the Lock switch on an SD card actually does?
I've presumed it switches something inside the card itself.
Well, thanks to getting my hands on an old transparent SanDisk SD card, I saw that the switch doesn't do that.
It is just a sliding tab. The actual electrical switch is inside the card slot of the camera, card reader, computer, wherever. The position of the card's switch just presses the REAL switch in the card slot, or not, depending on its position.
But BEWARE.....I discovered a couple of my cheapie USB-SD Card readers do not have the switch in them, and "locking" the SD card DOES NOT write-protect the card.
There's always something to learn about the technology we use, huh!

I did not know that! Thanks for the heads up! Although, I almost never flip the switch; but it is good to know for the 2 cards I did flip the switch on!

Nice to see constructive dialogue. I always use the lock switch when I switch SD cards cause I don't want to take the chance of losing photos.

Tu Tu true. (I never "got" Seinfeld. I suppose I'm too old and out-of-date... like my Brownie cameras.)

UHH member “nadelewitz” -
Respectfully, I suggest taking your question to websites for SanDisk, Delkin, etc.
What does it really matter what gets triggered where? The lock tab works.
I found his post wandering and lacking a clear answer to the question in the title.

Jeez, why are people making an argument out of this?
I OBSERVED AND TESTED what I was saying in the original post.
I HAVE card readers that DO NOT have the switch in the slot, and DO NOT prevent writing when the card is "locked".
Just trying to offer some advice that could save someone some aggravation.
You're welcome!
I doubt Bob was arguing with you and you seem too sensitive to respond to. Cassettes and video tapes have a plastic tab that can be broken off to prevent over righting the tape. Cards work on the same principle. The "switch" is in the device not the media.
I checked a bunch of my SD cards. They ALL have the switch. I opened an old one; nadeleiwz is right.

All of mine have the switch as well and it has saved my careless butt on more than one occasion.

Thank you for concurring in what I originally said. I hope rjaywallace gets it now.
Just don't engage. I typically do my best to ignore the snarky, no help commentary we sometimes encounter.
Bottom Line... with the Switch it Protects your Images if the Card is Filled Up & you have Priceless Images you have Shot on your Card & you don't have them Transferred to Computer, Storage, or Flash Drive.
When I Finish Using Up my Cards, I Lock Them so I don't by Accidentally Erase any of my Important Images, I'm Now Transferring to Flash Drive, & will Still Keep them for Master Copies, if Anything Happens to the Flash Drives.
As for the Older Cards that Came Out Around the Turn of the Century, when Digital Cameras were Taking Off, I Can't Speak for the Older Switches.

The title question is rhetorical.
OP was simply providing information on the mechanics of the lock switch.
One important take-away is that the lock does not always work it depends on the reader being used.
