To turn the power washer off press.
Power supply on off switch symbol.
Because it means that devices with that broken o symbol are not truly off until they are unplugged.
I know i line and o circle symbols are used to specify a switch that turn on and off the power supply.
Iec 60417 5009 the standby symbol line partially within a broken circle indicates a sleep mode or low power state.
The power switch is a rocker switch and it has two symbols on the face.
A flip of the switch in one direction turns the device on and a flip in the other turns the device off.
It does not really represent off it represents low power.
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.
Some older devices instead have a power switch that accomplishes the same thing as a hard power button.
Because i thought that it represent a power line that can be plugged on symbol and a closed line and thus without power supply but seen that in wikipedia said that it can come from 1 and 0 used in binary to represent on and off bits i don t know.
I on but the o is really an interrupted circle with a line through it.
Iec 5009 the standby symbol line partially within a broken circle indicates a sleep mode or low power state.
On off power button symbols i o.
The power switch on the back of the case is actually for the power supply installed in the computer.
My question is what is its origin.
Why is this important.
They are the international symbols for power on and power off.
