About the Power Button Rounded black outline icon
The standard standby mark: a circle broken at the top by a gap, with a short vertical bar rising through the opening, all drawn in rounded-cap strokes. It communicates power on, shutdown, restart and standby at a glance. Use it for device control panels, smart home and IoT app buttons, log out or sleep actions, hardware product diagrams, and appliance interface labels.
Proportions are generous, with the bar reaching just above the circle and the gap wide enough to stay open when scaled down. Rounded stroke ends give it a soft modern feel that matches toggle, settings and restart icons in the set. It works cleanly from 16px up in toolbars.
This is the black outline version of the power button rounded icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
