The 12 Volts was referring to the led voltage.... The switch is a 5A/250VAC

I'm not blaming you Randy, it's my fault, I just read the headline description and saw 12V so went and purchased a 12V switch. It seems though that would have worked ok (not sure for how long) the main problem was that I tried to supply the LED with a voltage and that then sent 240V into the board . My PC recognises when I plug the USB cable in but it no longer recognises the device like it used to so I guess I fried something in the USB system (driver/control chip?) The USB hub that my printer was connected to also died at the same time so it seems the 240V exited the board via the USB cable and into the USB hub.
