Abstract
An electromagnetic relay includes an exciting coil, a pair of fixed contacts, a movable spring, a magnet, and a yoke in contact with the magnet. The pair of fixed contacts is arranged along a first direction. The movable spring comes into contact with or moves away from the fixed contacts in response to the turn on or off of current to the exciting coil. The magnet prolongs the arc generated between the fixed contacts and the movable spring. The magnet is adjacent to the fixed contacts along a second direction orthogonal to the first direction, and is adjacent to the exciting coil along a third direction orthogonal to the first direction and the second direction. The yoke is adjacent to the fixed contacts along the third direction in a state where the yoke is in contact with the magnet.
