Individual switch-type power strips are among the most commonly used electrical devices in everyday life. As the number of electrical appliances increases, they have become essential. However, the number of related fires has also been rising, prompting case studies and reproduction experiments to determine the cause. The results showed that some fires occurred due to poor design of certain individual switches and due to users’ incorrect assumptions that led to misuse. Therefore, this study aims to identify the design problems and prevent user cognitive errors.
