An electromagnetic relay includes a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece including first and second contacts, a drive device including a coil, a case, and a magnet. The case includes an accommodation space accommodating the first fixed contact, the second fixed contact, and the movable contact piece, and a first arc extension space at least partially disposed between the coil and the magnet. The magnet is disposed so as to overlap with the coil in a third direction orthogonal to the moving direction and a longitudinal direction of the movable contact piece. The magnet configured to extend a first arc generated between the first fixed contact and the first movable contact and a second arc generated between the second fixed contact and the second movable contact in the longitudinal direction of the movable contact piece.

An electromagnetic relay includes a base, a fixed terminal, a fixed contact, a movable piece, a movable contact, a magnet, a base holder, and a case. The fixed terminal is supported by the base. The fixed contact is connected to the fixed terminal. The movable piece is supported by the base. The movable contact is connected to the movable piece and faces the fixed contact. The magnet exerts a Lorentz force on an arc generated between the fixed contact and the movable contact. The base holder is a separate body from the base. The base holder is attached to the base. The base holder is disposed in at least a direction in which the Lorentz force acts with respect to the base. The case is attached to the base holder.

An electromagnetic relay includes a base, a casing, a coil, a movable contact piece and two fixed contact pieces. Each of the fixed contact pieces includes a plate-shaped base. A portion of one side of the plate-shaped base extends outward and is bent to form a fixed contact fixing part. The fixed contacts are arranged on the fixed contact fixing part, and an abdicating through hole is defined in the base. The plate-shaped bases of the fixed contact pieces are respectively connected to an outer side surface of the base and spaced from each other. Each of the fixed contact fixing parts protrudes through the abdicating through hole and located between the base and the casing. Each of the fixed contacts faces to the movable contact on the movable contact piece, and a portion of the plate-shaped base on the fixed contact piece protrudes out of the casing to form a connecting part.

Provided is a relay having a structure for preventing deformation of a movable spring when it is caulked. A yoke of the relay has a protrusion for caulking inserted in the movable spring, and a bulge portion adjacent to the protrusion and having a height lower than a height of the protrusion. By providing the bulge portion to the yoke, the dimensional change in the caulking direction of the movable spring when the movable contact is caulked can be reduced.

A high-voltage relay includes a magnetic drive assembly having a first yoke and a second yoke spaced apart from one another, and an armature driven by the magnetic drive assembly. The armature is a rocker having a first arm and a second arm extending away from the first yoke. The armature can be tilted between an open position and a switching position and is mounted on the first yoke. The first arm has a switching contact assembly. A magnetic circuit including the first yoke and the second yoke is closed in the switching position by the second arm.
