Abstract:
The electromagnetic relay includes a fixed terminal, a movable contact piece, a drive device, a contact case, at least one magnet, and at least one yoke. The fixed terminal includes a fixed contact. The movable contact piece includes a movable contact disposed to face the fixed contact. The drive device moves the movable contact piece in a direction in which the movable contact comes into contact with the fixed contact and in a direction in which the movable contact is separated from the fixed contact. The contact case is made of resin. The contact case houses the fixed contact and the movable contact piece. The at least one magnet is disposed around the contact case for generating a magnetic field inside the contact case. The at least one yoke is fixed to the contact case.
