1. An electromagnetic relay comprising:
a fixed terminal;
a fixed contact connected to the fixed terminal;
a movable contact facing the fixed contact;
a movable contact piece connected to the movable contact, the movable contact piece being movable between a closed position at which the movable contact is in contact with the fixed contact and an open position at which the movable contact is separated from the fixed contact; and
a dust collecting mechanism disposed adjacent to the fixed contact and the movable contact, the dust collecting mechanism being configured to generate a second negative pressure greater than a first negative pressure generated between the fixed contact and the movable contact when the movable contact piece moves from the closed position to the open position.
