Why Use Normally-Closed Contact for Stop Buttons? - Inst Tools
A digital input, be it for PLC or any relay circuit, has two types of contacts – normally open (NO) and normally closed (NC). To design any electrical control circuit, a designer must be able to understand the difference between them and decide what to use for control.

2020年2月12日 · Get a pushbutton w/NO contacts, a PB w/NC contacts, and a 2-position selector switch with a set of contacts. Wire each of these to a PLC input module. Program a NO & NC contacct for each and watch how their states change. It should become clear to you then.
“NO”与“NC”,哪个是常开、常闭? - 百度知道
2024年7月19日 · 总结来说,"NO"代表触点在无信号时打开,"NC"代表触点在无信号时闭合。 理解这两个术语对于正确设计和使用电气控制系统至关重要。 “NO”与“NC”,哪个是常开、常闭? 在电路中,"NO"和"NC"是关于触点状态的术语,它们分别代表不同的功能。 NO,即常开触点,其特点是常态下触点是断开的,当电路接通时,触点才会闭合,类似于开.
