2024年6月25日 · How the I and O power button symbols were created. The IEC decided that the symbols to be used for power on and power off would be “I” and “O,” respectively. The “I” represents the binary 1, meaning on, whereas the “O” represents the binary 0, meaning off.

IEC 60417-5010, [10] the power on-off symbol (line within a circle), is used on buttons that switch a device between on and fully off states. A crescent moon, indicating sleep mode, is added by IEEE 1621 as a replacement for the standby symbol.

2024年11月30日 · The power button symbols "I" and "O" represent "on" and "off" respectively, while the standby symbol (⏻) is a combination of the two, and is neither fully powered nor completely dead. Discover the meaning behind the I/O power button symbols.

Understanding the On/Off Symbols. The power button displays two distinct symbols that embody its function: I and O. The vertical line within a circle (⏻) represents “ I,” symbolizing power is being supplied to the device (power ON). Conversely, a simple circle (⭘) denotes “ O,” indicating that no current flows through (power OFF).

2023年6月9日 · A power button turns an electronic device on or off. A hard power button visually indicates when something is on or off, unlike a soft power button.

2024年1月19日 · The on/off toggle switch on laptops typically features a line within a broken circle symbol. This symbol serves as a universal representation of the On/Off state, allowing users to power the device on or off with ease.

2024年1月2日 · Power button symbols on electronic devices convey essential information about the device, preventing accidental activation or deactivation that could lead to injuries. The classic power symbol, a circle, is commonly found on computers, laptops, and monitors, indicating the device's on/off status.

2024年12月31日 · One of the most recognizable aspects of the power button is the universal symbols used to indicate the on and off states of devices. At a glance, these symbols may appear simplistic, yet they convey important information and function as a form of non-verbal communication between users and machines.

2023年9月26日 · The On/Off Symbols: The power button typically features two common symbols: a vertical line enclosed within a circle ─ referred to as “I” (for “On”) ─ and a small circle, similarly enclosed ─ referred to as “O” (for “Off”).

2023年8月10日 · One of the most vital components of these devices is the power button – a small but powerful component that’s responsible for switching your devices on or off. In this article, we’ll explore the origins of the power button, the meaning behind its symbols, and how they became a universally understood language for electronic devices.
