The power switch on the back of the case is actually for the power supply installed in the computer.
Power supply on off switch symbol.
The switch does not fully disconnect the device from its power supply this may appear on a toggle switch opposite a power on symbol alone on a pushbutton that places the device into a standby state or alone on a button that switches between on and standby.
The power switch is a rocker switch and it has two symbols on the face.
To turn the power washer on press the down on the power switch.
Some older devices instead have a power switch that accomplishes the same thing as a hard power button.
It does not really represent off it represents low power.
To turn the power washer off press.
O means the power is off and means the power is on.
On off power button symbols i o.
Iec 5010 the power on off symbol line within a circle is used on buttons that switch a device between on and fully off states.
They are the international symbols for power on and power off.
Because it means that devices with that broken o symbol are not truly off until they are unplugged.
My question is what is its origin.
I on but the o is really an interrupted circle with a line through it.
I know i line and o circle symbols are used to specify a switch that turn on and off the power supply.
Why is this important.
Iec 5009 the standby symbol line partially within a broken circle indicates a sleep mode or low power state.
