MaintainedĪll switches fall into one of two distinct categories: momentary or maintained. Switch actuation can come from pushing, sliding, rocking, rotating, throwing, pulling, key-turning, heating, magnetizing, kicking, snapping, licking.any physical interaction which can cause the mechanical linkages inside the switch to come into, or go out of, contact. Push button, rocker, slide, and magnetic. Voltage, Current, Resistance, and Ohm’s Law.What is a circuit? - Especially know the difference between an open and closed circuit.Then come back, and we’ll have some fun button talk. If you’re not familiar with the following concepts, consider reading their tutorials first. The difference between normally closed and normally open buttonsīefore diving into this tutorial, make sure you’re up to snuff on the most basic of electronics knowledge.But how could we live without buttons and switches!? What good is a blinky circuit with no user input? Or a deadly robot with no kill switch? What would our world be without with big red buttons you should never, ever press. All they do is select between an open circuit and a short circuit. Switches don’t require any fancy equations to evaluate.
