    This is more or less the right answer. Electronics have active components. This is built completely off of passive components. Electromechanical would be a good description of it. Though the speed control isn’t electro mechanical. Physics and the Reed switch does set an upper limit of how fast it can trigger. But Tom just has a button that he holds. When button is down motor accelerates when button is not down motor is idle. So it’s more of a Tom speed controller.
