Which is the switch, off or on?

[Felix]

OFF and ON both belong to the switch keys. The OFF key means to turn off. The ON key means to turn on. A common example is the car light lever, where turning the knob to ON turns the lights on, and turning the knob to OFF turns the lights off. A button with a circled letter A and the word OFF below it is the auto start-stop function switch. Pressing it can turn the engine auto start-stop function on or off. ESPOFF refers to the electronic stability program off switch. When the ESPOFF switch is pressed, the ESPOFF icon will appear on the dashboard to remind the driver that "the ESP system has been turned off." When the car leaves the factory, the default setting is to turn on the ESP system when the ignition is on. Therefore, when the ESPOFF button is lit, it means this function is not activated; when the button is not lit, which is the default state of the vehicle, it means this function is activated. Most driving assistance systems in cars today are turned on automatically, so some buttons have a pattern with OFF written below. Pressing OFF means turning off the corresponding assistance system. There are some buttons in the car that are not recommended to be pressed randomly: The automatic handbrake button, especially while driving, can be very dangerous. The ESP button. ESP can only be turned off under the following circumstances: when the vehicle is stuck in mud or sand during off-roading; when aggressive driving is required (e.g., drifting); when the vehicle is equipped with snow chains. The drive mode button. On some rough and difficult roads, this button can be pressed. During normal driving, the default state is optimal. In fact, not only in cars are OFF and ON used as switches, but they also mean the same thing on other items. Many household appliances we use daily have these words.
