Power black outline icon
Power button symbol: open circle with a vertical bar rising through the top gap
About the Power black outline icon
The standard power symbol, drawn as a wide open circle with a gap at the top and a separate vertical rounded bar rising through that gap. Both ends of the arc are capped rather than joined, leaving the bar free standing. It is the expected mark for on and off controls in device dashboards, settings menus, shutdown and restart dialogs, smart home apps and hardware product pages.
The generous gap and thick rounded strokes make the two elements read as one glyph even at button sizes, and the bar sits slightly above the circle for extra clarity. Pair it with restart, sleep and plug icons in a device control set; at 16 px the shape still holds, so use it directly inside toggle buttons.
This is the black outline version of the power icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
