I just found an article[1], which advises that,
"SD Cards, while they have a write-protect switch, are actually no good for this purpose because it’s not actually hardware write protection – at best the card reader sends a signal to the operating system that the drive should be treated as read-only."
"It is the responsibility of the host to protect the card. The position of the write protect switch is unknown to the internal circuitry of the card."
"Basically this means that either a) cheap card readers that lack the sensor or b) operating systems or malware that don’t respect the 'please don't write to this disk' flag can write to the drive."
