What does ⏻ mean?

The ⏻ symbol, designated in Unicode as POWER SYMBOL (U+23FB), is the world's most ubiquitous electronics graphic. Standardised under IEC 60417-5009 as the "standby" symbol, the mark overlays the binary digit 1 (representing "on" or power flow) onto the binary digit 0 (representing "off"), with the line interrupting the top of the circle. Because modern consumer devices enter low-power standby sleep states rather than disconnecting fully from mains power, ⏻ has become the universal emblem for power buttons on computers, smartphones, appliances, and cars. Compare it with the eject symbol ⏏ and diameter symbol ⌀ in our technical symbols directory.

Common uses

  • Power buttons: embossed on physical buttons and capacitive touch sensors of computers, displays, and gadgets
  • Operating system interfaces: marking software shut-down, restart, and power-options menus
  • Automotive interfaces: labelling ignition start/stop buttons in modern keyless vehicles
  • Energy standards: used by agencies like Energy Star to signify standby power modes and energy conservation

Frequently asked questions

What is the difference between ⏻ and ⏼?

⏻ (IEC 5009) features a line breaking through the circle and represents a standby toggle, meaning the device stays partially energized in sleep. ⏼ (IEC 5010) features a line completely enclosed inside a full circle, representing a true on/off switch.

Where did the 1 and 0 design come from?

Engineers adopted the binary digits 1 and 0 from Boolean logic during World War II to indicate closed (on) and open (off) electrical circuits across international borders, avoiding language-specific labels like "On" and "Off".

Is there an alt code for the power symbol?

No. ⏻ is outside the Windows-1252 and code page 437 character sets, so no Alt + number code produces it. Copy it from this page, type 23FB then Alt + X in Word, or find it in Character Map.

How do I type the power symbol on a Mac?

There is no single Option shortcut for ⏻ on the US layout. Press Control + Command + Space to open the Character Viewer, search for “power” and double-click it, or copy it from this page.

What is the HTML code for the power symbol?

⏻ has no named HTML entity. Use the numeric reference ⏻ or ⏻, or paste the character directly into a UTF-8 page.

What is the Unicode for the power symbol?

⏻ is U+23FB, officially named POWER SYMBOL, in the Miscellaneous Technical block. It has been part of Unicode since version 9.0 (2016).
