A push button switch works by closing or opening an electrical circuit when pressed. When the button is depressed, it bridges a gap between contacts, allowing current to flow and completing the circuit. Releasing the button breaks the circuit, stopping the current. This simple mechanism is used in various applications, from household devices to industrial controls.
