Thank you. Admittedly I haven't had the opportunity to try this in a classroom yet - but yes, children being children will probably revel in trying to get the Red Zone to light up, I was conscious of this. That's one of the reasons why the counter displays are a good addition because they could represent how many seconds/mins they lose from break or golden time.

Thanks for sharing your expertise.
It's been interesting to hear everyone's suggestions for improvements, I think the idea of this build has gotten people's creative juices flowing, which has been great to hear.I'd love to see other incarnations of this idea.
Nice idea. Great thinking regarding adapting it for U.S switches.
Yes, I did think of something similar, but I had MDF to hand and, because it's made of small fibres, it's easy to chisel (comes away just like thick cardboard).Your solution would be great for a varnished wood finish.
I think you can buy them for the US switches (https://www.amazon.com/Frankenstein-Style-Switch-Plate-Cover/dp/B01GOH9UZS) - these aren't the same as mine, hence why I made one.
But doesn't the existing plastic covering act as that barrier anyway? - it's a cover over a cover, so to speak.
Yes, that would be a nice touch.
Like this (image attached) - but will vary based on the spacings and the switch type etc.

Thanks, admittedly it's just resting there. I was thinking it could be 'no more nails'-ed on or perhaps some strong double-sided tape. I haven't got around to this part yet.
