Electromagnetic relay

Abstract

An electromagnetic relay includes a fixed terminal, a fixed contact, a movable contact, a movable contact piece, and a dust collecting mechanism. The fixed contact is connected to the fixed terminal. The movable contact faces the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is 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. The dust collecting mechanism is disposed adjacent to the fixed contact and the movable contact. The dust collecting mechanism generates 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.
