Last time i wrote a post about normally open switch and this post is about the normally close switch or NC switch. A NC or normal close switch is a switch which have close electric circuit in normal state. Or we can said that normal close push button switch is switch which is close electric contact in normal state and when we push it then switch make a open contact or open circuit.
