Does the letter 'on' represent on or off?

The letter 'on' represents on. Pressing the 'on' button activates the function, while the corresponding 'off' button is the shutdown key, which pauses the function when pressed. Car function buttons are categorized as follows: 1. 'mute' is the mute button, used to control the mute mode of multimedia; 2. 'mode' is the mode button, used to switch multimedia modes; 3. 'gps' is the locator, used for vehicle positioning, tracking, playback of driving routes, electronic fencing, and fuel monitoring; 4. 'set' with an exclamation mark is the tire pressure monitoring button, which triggers an alarm if tire pressure is insufficient; 5. 'sync' is the dual-zone air conditioning adjustment, lighting up indicates synchronized temperature adjustment, while turning it off allows separate adjustment of air conditioning temperatures on both sides.
I saw the switch labeled 'on,' which means it's turned on, not off. This marking is very common on electrical appliances, such as desk lamps, electric fans, or the mute switch on a phone. When you toggle it to 'on,' the device starts up. Once, my child's newly bought toy car had a power button in English, and she thought 'on' meant off. As a result, the battery drained overnight, and the toy couldn't be played with the next day, wasting money. So, every time I teach someone, I emphasize that literally, 'on' means to start or operate, while 'off' means to shut down or stop. Learning to recognize this marking can avoid a lot of trouble, especially since many modern devices follow international standards. Not understanding it may lead to operational errors, potentially damaging the machine or increasing usage costs. I recommend practicing with physical objects, like testing the switches on kitchen appliances, to reinforce memory.
I believe the 'on' marking on devices indicates the active state, which originates from the English usage meaning 'operational.' In daily life, you can find this on computers, televisions, or car control panels—turning to 'on' connects the circuit and activates the device, while 'off' cuts the power and stops operation. I've noticed that some domestic appliances might mix Chinese labels, but switches with 'on' are more commonly used in imported brands. Accidentally mistaking 'on' for 'off'—such as leaving a garage door open or failing to activate a security alarm—could pose safety risks or energy waste. I recommend users develop the habit of carefully checking labels before each use and reading the manual for newly purchased items to confirm their meanings. Remembering this can improve efficiency and reduce potential issues.
When I was learning English, I knew that 'on' means to turn something on, and 'off' means to turn it off. In the use of electrical appliances, such as a hair dryer, when the switch is turned to 'on', it blows hot air, and when it's 'off', it stops. Once, a classmate's dormitory air conditioner remote control had buttons labeled in English, and he mistakenly thought 'on' meant to turn it off, resulting in the air conditioner running all night and the electricity bill exceeding the limit. Such misoperations are quite common, especially among people who are not familiar with the language. It is recommended to frequently use devices with such switches in daily life to gain experience and avoid similar situations. Simply put, 'on' means to turn on, so always double-check before operating.
