I don't think anyone else found it, but there's a way to skip having to go to the switches to deactivate in gadget training so you can get complete in less than 8 seconds IGT.

How it is done do Xray Gadget and when deactivating the switches press them twice. Then the next time you do Xray gadget upon getting them from the table immediately textboxes in the corner say they have been deactivated. Then shortly later it completes.

At the same time I also found that if you do night vision gadget and then the next time you do it immediately entering the darkness the textbox shows up. Instead of having to go to the switch. Sure it may not seem like that much of a time save. But it still is something.
