Unfortunately that's not the case, the 'hardware' switch on an SD card
is just a flag that operates a switch in the card slot. Even if this is
in the write protect position it won't stop data being corrupted or
going corrupt if the flash card or reader is at fault.

But it will stop a normally working reader attempting to write data to the
card, almost certainly over stuff that could otherwise be recovered. It's
not perfect but it is another level of protection to the data you want
back, so why not use it?

No it won't.
The readers are also pretty dumb and its the software that has to take
notice.
Something not all software does do.
