About the Round Power Button black filled icon
The universal power mark sits centered inside a large outer circle: a thick ring broken at the top with a short vertical bar rising through the gap, giving the classic on off standby glyph a physical button housing. It fits device control panels, app shutdown and logout menus, smart home switch tiles, appliance interfaces, remote control layouts and hardware product documentation.
Three concentric elements set the rhythm, with the outer frame, the interrupted inner ring and the rounded upright bar all sharing one stroke weight. The vertical bar overlaps the ring gap cleanly so the symbol stays legible when scaled down. Pair it with restart, sleep and settings icons, and keep it at 24px or above so the gap does not close.
This is the solid black filled version of the round power button icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
