It is much easier than you diagram makes it out to be. There is a thing called a y harness. All it is a receptacle for two servo leads on one end, with a servo plug on th other. You plug both items that you want to run from the same channel in the receptacle, and plug the servo plug into the receiver. In your case, you would plug the esc and receiver pack into the receptacle, and plug the servo lead of the y harness into the switch and plug the switch into the channel two section of the receiver.
