What happens when a pushbutton switch with N.O. Contacts is activated?

A pushbutton switch with normally open (N.O.) contacts is designed to remain open until it is activated (pressed). When the switch is pressed, it closes the circuit, allowing electric current to flow through. This is why the correct answer is that it creates a closed circuit.

In contrast, when the switch is not pressed, the circuit remains open, and current cannot flow. The function of an N.O. contact is to momentarily close the circuit while the button is pressed; when released, the contacts return to their normal open state. Understanding this mechanism is crucial for implementing pushbutton switches effectively in various applications, ensuring that devices switch on or off as intended when interacted with.
