The switch assignment reminded me of Fischli and Weiss’s “The Way Things Go”, which is a 30 min long chain reaction.  In a way, I percieved every action here a switch for the next action, because they all trigger the start of eachother. But of course  a switch is something that closes a loop or a circuit whereas in  “The Way Things Go”  the chain reaction doesn’t close a certain loop, it is a line of actions following eachother.
