About the On Off Power Button black outline icon
A thick ring is left open at the top, where a short upright bar rises through the gap — the universal power mark for switching something on or off. It communicates standby, shutdown, restart and sleep at a glance. Use it on device mockups, settings and smart-home dashboards, log-out menus, remote-control layouts and slides that explain starting or stopping a process.
Strokes are even in weight with rounded caps, and the bar sits centered so the negative space at twelve o'clock stays clean. It sits naturally beside plug, battery, switch and socket icons in the same set. Keep it at 24 px or larger so the top gap does not close up.
This is the black outline version of the on off power button icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
