WebWhen a button is open until actuated, it’s said to be normally open (abbreviated NO). When you actuate an NO switch, you’re closing the circuit, which is why these are also called “push-to-make” switches. Conversely, if a button usually acts like a short circuit unless actuated, it’s called a normally closed (NC) switch. Webnormally-closed in Electrical Engineering. ( nɔrməli kloʊzd ) adjective.
