Analysis case of faulty switch contacts

Appearance inspection, electrical verification, and internal observation using X-rays conducted! Introduction of analysis cases.

Since a malfunction was suspected at the switch part of the appliance that would not power on, we will introduce analysis cases along with the work flow. First, we check for any shape changes such as swelling, cracking, or discoloration through visual observation. In the electrical check, we confirm whether the malfunction can be reproduced and whether it is an open or short circuit. Internal observation using X-rays revealed that the contact terminals inside the switch had melted, scattered, and disappeared, resulting in an open failure. Ultimately, we will submit a report that includes an analysis of the cause. We also welcome inquiries regarding analysis consultations after non-destructive testing, so please feel free to reach out. 【Basics of Non-Destructive Observation】 ■1: Visual Confirmation ■2: Electrical Confirmation ■3: Internal Observation with X-rays *For more details, please refer to the PDF document or feel free to contact us.
