What is Normally Close Switch and How NC Switch Work

Last time I wrote a post about a normally open switch and this post is about the normally close switch or NC switch. An NC or normal close switch is a switch that has a close electric circuit in a normal state. Or we can say that normally close push button switch is a switch which is close electric contact in normal state and when we push it then switch make an open contact or open circuit.

I hope this post not required a lengthy explanation and we can explain it using one symbol diagram.
