About the Power Button Circle black outline icon
This icon shows the standard power mark, a short vertical bar breaking through the top of an open ring, placed inside a second thin circle that acts as a button frame. The double-circle build reads as a physical key you can press rather than a bare glyph. It fits shutdown and restart menus, smart home and IoT device controls, appliance panels, standby toggles in dashboards, and start screens for hardware or automotive interfaces.
Both rings use an even stroke weight and the inner mark sits centered with generous padding, so the glyph stays legible when scaled down to a toolbar. It pairs with settings, restart, sleep and plug icons in a system control set. At very small sizes prefer the fill style, since two concentric thin circles can blur together below 20px.
This is the black outline version of the power button circle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
