Review on TWTADE Electromagnetic Indicator Assurance Years）YJ4N GS by Chris Cruz

Relay clicked and its indicator lit, but normally open connections were not closed. Troubleshooting showed that the problem was in the outlet. Its screws were not connected to the pins of the actually closed relay. A simple factory quality control could easily sort out a defective part. On the contrary, the end user is the one who suffers frustration and delays when receiving a working product.
