[0002] An electromagnetic relay is an electronic control device with a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits. It is essentially an "automatic switch" that uses a smaller current and lower voltage to control a larger current and higher voltage. Therefore, it plays a role in automatic regulation, safety protection, and circuit conversion in circuits.

[0003] When a problem occurs with an electromagnetic relay, it is necessary to test the electromagnetic relay to see if it has failed. Existing tests mostly use a probe test board corresponding to a relay coil pin specification. However, there are many types of relays, resulting in many types of coil pin specifications. This requires the processing of multiple probe test boards, which is costly and inconvenient to manage and store. Therefore, we propose an electronic device failure detection device to solve the above problems. Utility Model Content
