What is the result when a pushbutton switch with N.O. contacts is activated?

When a pushbutton switch with normally open (N.O.) contacts is activated, it creates a closed circuit, allowing current to flow through the circuit. Normally open contacts are designed to remain open (non-conductive) until the button is pressed. When the button is pressed, the contacts close, bridging the gap and completing the electrical path. This allows electrical energy to pass through the circuit, powering any connected devices.

The terminology is key here; "closed circuit" indicates that the pathway for electric current is complete, while the term "open circuit" would mean no current flows. In contrast, "short circuit" refers to a situation where electrical current bypasses the intended pathway, potentially causing damage. "Ground circuit" is unrelated to the action of the pushbutton switch and pertains to grounding systems in electrical setups. Thus, when the switch is engaged, the result is indeed a closed circuit, enabling the flow of electricity.
