This is pretty much the best solution ITT. They are durable, transportable, can be velocity sensitive, and easy to replace should one fail. Much more so than needing to remove a skin to get access to the switch/flimsy piece of wire at least.

They are so effective they are already in common use. Pic related, Drum triggers. Used to open and close compressor gates when recording, and, to trigger lights via DMX controllers. Rig each to an op-amp, and have the output of said op-amp trigger a driving transistor to run your lights.
