Another way to look at this is that while the Behavior PowerChange is continuous, once it gets wired up to a switch or something, the reaction to the Behavior at any point may change the state of the switch (particularly if something else might have affected the state; including eg some human pressing a physical button). So a Behavior PowerChange is the potential changes that might occur.
Still, I will think about renaming PowerChange, perhaps it could be clearer.
