A door 5 having a holding fulcrum 7 and arranged to cover the voltage selection switch 4 is provided with a square window 6 to which a transparent mylar is attached, so that the current voltage setting state can be understood. As described above, when the door 5 covers the entire voltage selection switch 4 in this way, the voltage switching operation cannot be performed.

FIG. 2 shows the power supply unit of the OA equipment including the power supply unit according to the present invention and the power switch 3.
The surrounding area is shown with the power cable 1 inserted in the plug inlet 2. Although the door 5 is omitted in the same figure for the sake of clarity, the power supply unit part shown without removing the door 5 is shown in FIG.
It is FIG.
