3. Origins of Accident

According to the inquiry, the slide switch was returned just midway and not completely turned off, the user misunderstood the state of its stopped at the medium position for the state of its turned off, and left the hair drier with the switch left midways.

The electrical contact of this slide switch was also partially poor so that in the switch position where the user left it, the heater was energized, while the blowing fan motor was not energized. The heater was heated with the blowing fan non-rotated so that the lead wire overheated, the coating was melt and short circuited so as to ignite to combustibles.

Though the hair drier is provided with a device for preventing the temperature from raising too much, the hair drier was left with its hung on the metal hook, which prevents the heat from being transmitted to the prevention device and the prevention device could not functioned well.
