Well, I suppose you could make it one, but I'm not sure what that would accomplish. One doesn't need to talk about a switch, or the movement of a switch, or even a toggleSwitch() method, in order to effect a state change with the bulb, because the interaction style is one of *state transfer*; if I want to turn the bulb on, I just do a HTTP PUT containing a representation of the "on state" to the URI identifying the lightbulb.
