Web13 de ago. de 2015 · Normally Open is when the circuit is open or in other words off. So when you hear normally open it basically means that it is momentary on. So it is off all the time unless the switch or relay is in use and then it "closes" the circuit to turn it on and when released it returns to the off position. For example a window switch in your car, it ... WebA closed-circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch. The terms ”open” and ”closed” refer to switches as well as entire circuits. An open switch is one without continuity: electrons cannot flow through it.
