In a normally closed switch, the circuit is closed (connected) when the button is not pressed, and it is open (broken) when the button is pressed.

Push button switches are commonly used in a wide range of electronic and electrical devices, such as power tools, appliances, computers, and industrial control systems. They are also used in many everyday applications, such as doorbells, elevator buttons, and emergency stop buttons.
