power button
On-off control point
A power button is the control that turns an electronic device on or off.
On computers, phones, and appliances, pressing it toggles between powered and unpowered states—or on modern devices, between active and sleep modes.
The symbol is typically a circle with a vertical line through the top: Hold the power button for ten seconds to force a restart.
