Which is the power button, off or on?

[Karl]

on means on, off means off. Introduction to ON/OFF is as follows: Introduction to on and off: Refers to an electronic component that can open a circuit, interrupt current, or divert it to other circuits. The most common switches are manually operated electromechanical devices with one or more electrical contacts. "Closed" contacts indicate that the electrical contacts are conducting, allowing current to flow; "open" contacts indicate that the electrical contacts are not conducting, forming an open circuit and preventing current flow. Introduction to ESP-OFF/ON: ESP-OFF refers to the electronic stability program off switch. When the ESP-OFF switch is pressed, an ESP-OFF icon will appear on the dashboard to alert the driver that "the ESP system has been turned off." By default, vehicles are set to activate the ESP system upon ignition. Therefore, when the ESP-OFF button light is on, it indicates that this function is not activated; when the button light is off, which is the vehicle's default state, it means the function is turned on.
