Power on-Off Symbol

Power on-Off Symbol at U+23FC is a technical symbol for a single control that toggles equipment between on and off states. It sits in the Miscellaneous Technical block and represents the combined power function often shown on push buttons, remote controls, appliance panels, and software status icons. Its main real-world use is in interface labeling, especially where one button both starts and stops a device rather than having separate on and off controls. You may see it in manuals for computers, monitors, audio gear, power strips, lab instruments, and consumer electronics to identify the standby or power-toggle button. It also appears in icon fonts, accessibility labels, technical documentation, and UI mockups when designers need the standardized power-toggle mark as text. The symbol is related to the more familiar broken-circle power emblem, but this character is specifically the Unicode text form, so appearance can vary noticeably by font and may be missing in older or minimal symbol fonts.
