Is the switch off or on?

[StHenry]

on means on, off means off. Here is some relevant knowledge about car switches: How to use the light switch: Most light switches are located on the left combination switch. Up is the right turn signal, down is the left turn signal. Forward is high beam, backward is the switch between high and low beam. Rotating the head of the combination switch forward once turns on the parking lights, and further forward turns on the headlights. Usage of high and low beams: The low beam switch is used for normal night driving in urban areas or under streetlights; the high beam switch is not allowed for night driving in cities. The flash switch, which alternates between low and high beams, is used for warning purposes such as when the other driver doesn't dim their lights. When passing through intersections at night, most often the light adjustment lever is lifted upwards.

I've been asked this question many times. Those small buttons on the car's center console with 'ON' and 'OFF' labels honestly confused me when I first started driving. What I remember most clearly is turning on the fog lights on rainy days: when you press the button and see the small light next to 'ON' illuminate, that means it's activated. Conversely, if the button backlight turns off showing 'OFF' status, that means it's deactivated. Basically all electronic device switches in the car follow this rule, including seat heaters and air conditioning. When you're really unsure, checking the button's backlight is the most straightforward way to tell.

Every time I wash the car, I have to deal with these labels. The automotive engineers were clever in their design—all function buttons are in the working state as long as they display 'ON' and are illuminated. For example, the driving mode switch button, when pressed, lights up an orange indicator next to 'ON,' indicating that sport mode is activated. Interestingly, some cars now feature touchscreens where a light tap changes the icon's color—blue means off, and red means on, making it easier to distinguish than the old-fashioned buttons.

During driving lessons, the instructor emphasized: 'OFF' indicates the device is in sleep mode, with the button's backlight dim; 'ON' means it's in operation, with a small light illuminated beside it. For instance, the rearview mirror heating switch requires the 'ON' light to be on for it to be effective when defogging in winter. Nowadays, new cars even feature dual-color indicator lights—green for active and gray for inactive—making it especially noticeable. A quick glance at a red light lets you know which functions are running, helping to avoid unnecessary battery drain.

Last week while helping my bestie pick a car, I noticed Hyundai's button design has evolved significantly. Traditional switches show dimmed characters when 'OFF' and light up when 'ON'. The latest trend replaces text with symbols - power buttons now feature circular lighting, with blue rings indicating 'OFF' and red rings for 'ON'. Some models even apply this to start-stop systems, displaying green circles on the dashboard when the engine idles at red lights, making it extremely intuitive.

The logic of car buttons is quite similar to that of home appliance remote controls. For example, when you press the rear window defogger button, you hear a 'click' sound and the yellow light turns on at the 'ON' position, indicating it's activated. Interestingly, designs vary among different car manufacturers: German cars prefer text labels with backlighting, while Japanese cars often use lever switches with indicator lights. When driving older models, you'll notice the position of physical switches—pushing up turns it on, pressing down turns it off, and the indicator light provides a more reliable confirmation.
