If the temperature of any of these heater elements reaches a critical point, a normally-closed switch contact will spring open. 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.

WebEach key of a computer keyboard, for example, is a normally-open "push-to-make" switch. A "push-to-break" (or normally-closed or NC) switch, on the other hand, breaks contact when the button is pressed and makes contact when it is released. An example of a push-to-break switch is a button used to release a door held closed by an electromagnet. WebHá 1 dia · The symbol for a “normally open held closed” state indicates that the contact has been wired as a normally open contact, but when the circuit is put into its normal off state, part of the machine keeps the contact closed.
