About the Power Button Circle black outline icon
The standard power symbol, a broken ring with a vertical bar rising through the gap, sits centered inside a second larger circle that frames it like a physical button face. It reads as on, off, standby and restart. Use it for device controls, smart home apps, admin dashboards, kiosk screens and hardware product pages.
Two concentric circles create a clear target area, and the gap in the inner ring lines up exactly with the bar for a balanced silhouette. It pairs with settings, restart and lock icons. Give it a generous tap target, at least 44 px, on touch screens.
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.
