Is 'off' or 'oN' the on or off position?

OFF and ON on machine switches: ON means on, OFF means off. Additional information: 1. Switching power supplies utilize modern power electronics technology to control the ratio of switch tube turn-on and turn-off time to maintain a stable output voltage. A switching power supply generally consists of a pulse width modulation (PWM) control IC and MOSFET. 2. Compared to linear power supplies, the costs of both increase with output power, but at different rates. 3. At a certain output power point, the cost of a linear power supply becomes higher than that of a switching power supply, known as the cost reversal point.
I remember when I first bought my car, I was also a bit confused by those switch markings, like 'off' and 'on'. Actually, 'off' means to turn off, and 'on' means to turn on, which is very common in cars, especially for light control switches. For example, when you park and rest, you should switch the headlights to the 'off' position to avoid draining the battery; when driving on the road, switch them back to 'on' to illuminate the road ahead and ensure safety. I made a mistake once—the lights didn’t turn on at night, and I could barely see the road. Luckily, I corrected it in time. The car manual emphasizes this: get into the habit of checking the switch status, especially during night driving, as having the lights on ensures other vehicles can see you. New drivers always have little hiccups at first, but with a bit more practice, it becomes second nature.
In car settings, 'off' means deactivated and 'on' means activated. These markings are designed to be simple and intuitive, helping to reduce operational errors. For example, the headlight button: set to 'off' during daylight to save power, switch to 'on' at night or when entering tunnels to ensure visibility. Having driven several models, I've noticed switch layouts vary slightly between brands, but the off/on principle remains consistent – unfamiliarity may lead to accidental activation. Developing proper habits is crucial. There was an incident where someone mistakenly turned off headlights in foggy conditions, causing a rear-end collision. Therefore, regularly consulting the vehicle manual and habitually verifying switch positions can enhance driving safety. Simply put, just remember 'off' for deactivated and 'on' for activated.
