I think this is actually unique. Reading the initial post, I don't think it's been suggested before. Good job, and I think it could be incredibly useful.
Faster wire is the worst bug in TPT. The switch did that before. But now it doesn't, because of that much glitches(if a spark was on the switch when it was turned off, it turned on again etc)
Not to complain but there's nothing really wrong with the current electronics system. Making all the electric automata faster in every element without breaking things that would be painful to fix might not be doable.
Making it slower might, but at the moment the slow speed is to ensure that things don't loop over on themselves. Have you ever tried sparking bubble water? :P
