Claims (1)

고정접점과 여기에 대향하는 가동접점으로 구성되고, 항시 열려있는 접점장치와 항시 닫쳐 있는 접점장치중 어느 일방을 타방의 양측부에 배설함과 동시에 고정접점과 가동접점간의 발생하는 아아크를 취소(吹消)하는 자기취소장치를 구비한 직류전자 접촉기에 있어서, 자기취소장치의 자석을 양측부의 접점장치에 근접하여 배설하고 양측부의 접점장치의 접점간을 작동시킴과 동시에 자석의 자기방향을 동일방향으로 함으로써 중간부의 접점장치의 접점간을 작동시킴을 특징으로 하는 직류전자 접촉기.It consists of a fixed contact and a movable contact that is opposite to it, and either one of the open contact devices or the normally closed contact devices is disposed on both sides of the other, and the arc generated between the fixed contact and the movable contact is canceled. In a direct current electromagnetic contactor having a magnetic canceling device, the magnets of the magnetic canceling device are disposed close to the contact device of both sides, the contact between the contact devices of both sides is operated, and the magnetic direction of the magnet is made the same direction. DC contactor, characterized in that for operating the contact between the contact point of the intermediate part. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
