Power Symbol Icon - Universal On/Off Sign for Digital Interfaces #93855 (License: Personal Use)

This minimalist black-and-white power symbol consists of a vertical line centered within an incomplete circle, universally recognized as the “on/off” indicator for electronic devices and software interfaces. Its design originates from the IEC 5009 standard and is widely adopted in consumer electronics, operating systems, and web applications. The icon’s simplicity ensures scalability and legibility across all screen sizes and resolutions.

Used in UI/UX design for power buttons, system settings, mobile apps, and hardware interfaces; matches user intent to control device state (turn on/off, restart, sleep). Commonly found in tech documentation, e-commerce product pages, and developer asset libraries.
