An electromagnetic relay includes a housing, a first fixed terminal, a movable contact piece, a drive device, and a first heat dissipation member. The first fixed terminal protrudes from inside the housing to outside the housing. The movable contact piece is disposed in the housing. The movable contact piece faces the first fixed terminal. The drive device moves the movable contact piece in a contact direction and an opening direction. The first heat dissipation member is disposed outside the housing. The first heat dissipation member is provided separately from the first fixed terminal. The first heat dissipation member is connected to the first fixed terminal.

Electromagnetic relay

An electromagnetic relay includes a housing, a movable contact piece, a first fixed terminal, and a drive device. The movable contact piece is disposed in the housing. The first fixed terminal includes a first contact portion and a first terminal portion. The first contact portion faces the movable contact piece in the housing. The first terminal portion protrudes out of the housing. The first terminal portion has a bent shape. The drive device moves the movable contact piece in a contact direction and an opening direction.

An electromagnetic relay includes a housing, a first fixed terminal, a movable contact piece, and a drive device. The first fixed terminal includes a first main member and a first layer member. The first main member protrudes from inside the housing to outside the housing. The first layer member is provided separately from the first main member. The first layer member is laminated on the first main member. The first layer member protrudes from inside the housing to outside the housing. The first layer member has a shape branched from the first main member. The movable contact piece is disposed in the housing and faces the first fixed terminal. The drive device moves the movable contact piece in a contact direction and an opening direction.

An electromagnetic relay includes a movable iron core arranged to move up and down within a center hole of an electromagnet unit formed by winding a coil, and a contact switch where an upper end surface of the movable iron core attaches to and detaches from a lower end surface of a fixed iron core arranged in the center hole according to magnetization and demagnetization of the electromagnet unit and a movable contact attaches to and detaches from a fixed contact by a movable shaft which reciprocates along with the movable iron core where the movable iron core includes a sliding portion which always abuts an auxiliary yoke disposed within a yoke, and where a height dimension of the sliding portion is at least equal to or larger than a plate thickness dimension of the yoke.
