The mechanism is pretty simple, I didn't manage to take a picture though, so some description must do.
There is a single axle inside that connects all three moving elements by three arms, each blocking one from movement. When the button is pressed, it twists the axle a bit, which turns the arms to release everything at once.
Once they are unblocked, the thieves turn around thanks to normal rubber bands, whereas in the trap it's all up to gravity
Hope that satisfies your curiosity, as a fun-fact I may say that it took me even longer than the cathedral itself to make it all work properly. But after taking everything apart and starting anew, all began to work. That relief...
