摘要： An electromagnetic relay which is improved in arc blocking performance without being increased in size is desired. An electromagnetic relay according to the present invention is provided with a fixed contact, a moving contact which is movable respect to the fixed contact, a pair of magnets which is arranged at the side of the fixed contact and the moving contact so that pole faces with mutually reversed polarity are separated from and face each other and a pair of arc cooling plates which is arranged in a spaces between the magnets and which has first surfaces which face each other across a gap and second surfaces which face a pole face of either of the magnets, respectively.

摘要： An electromagnetic relay includes a first stationary contact; a second stationary contact that is aligned with the first stationary contact in a first direction; a first movable contact that is movable toward/away from the first stationary contact in a second direction perpendicular to the first direction; a second movable contact that is movable toward/away from the second stationary contact in the second direction; and a first permanent magnet and a second permanent magnet that face each other. A first contact part, formed by the first stationary contact and the first movable contact, and a second contract part, formed by the second stationary contact and the second movable contact, are interposed between the first permanent magnet and the second permanent magnet in the first direction. The first permanent magnet and the second permanent magnet extend in a third direction, which is perpendicular to the first direction and the second direction.
