Flash Drives w/write protect switch?

Anyone know of current models with the tiny write protect switch? My
old 256mb Transcend has one but my 4GB Kingmax & Corsair's don't - is
this a no longer included feature?

Closest I can find is this:

But it looks like the lock prevents files being viewed, rather than a
simple write protect aka Read Only mode.

 

At least one (imation) comes with software to lock it, rather than a switch.
I suspect because there's nowhere on the body of the thing to mount a switch
... it's too small..

Will a software solution work for you or is there a specific reason for
needing a switch ?

 

A switch would be easier In a nutshell, I put my flash drive w/
anti-malware tools, etc, into an infected PC (I had no idea how messed
up the PC was) and it was kind enough to infect most of the .exe files
on it... then when I plugged it into my PC it slipped though the AV
and wreaked a little havoc there. Was only alerted that something was
suspect when my firewall claimed most of my internet apps had changed
since last use :-( Did a manual scan, and Hello!
