合金で構成されて、常時は上記窓孔を閉塞し、上
記ケース内の電磁石ブロツクにおける磁気回路部
の発熱時に上記窓孔を開放する作動片を該磁気回
路部に固定したことを特徴とする電磁継電器。 A window hole is formed in a case made of synthetic resin, and an actuation piece is made of a shape memory alloy and normally closes the window hole, but opens the window hole when the magnetic circuit section of the electromagnet block inside the case generates heat. An electromagnetic relay, characterized in that: is fixed to the magnetic circuit section.
