It is difficult to widen the dimensions, and it is difficult to construct a small and highly conductive relay.
- the conventional electromagnetic relay as shown in Patent Document 2 has the following problems due to the structure in which the make fixed contact terminal and the backstop are attached to the collar portion of the coil bobbin. That is, the first problem is that when a failure occurs during the operation in which the movable contact and the make fixed contact are connected, the coil bobbin collar is caused by the heat generated by the coil and the heat generated by energization of the movable contact spring and the make fixed contact terminal. This part melts and is fixed in a state where the movable contact is connected to the fixed contact, and there is a possibility that the current continues to flow without being cut off. That is, the fail safe at the time of failure is insufficient.
