摘要： 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.

摘要： This contact device includes: a first fixed terminal; a movable contactor configured to contact the first fixed terminal and separate from the first fixed terminal; a spring disposed below the movable contactor and formed of a metal; a holder including a bottom and disposed to position the bottom below the spring; and a resin member configured to cover a portion of the bottom of the holder. The holder has a higher thermal conductivity than a thermal conductivity of the resin member. The upper surface of the bottom of the holder includes an exposed portion that is exposed from the resin member. The spring is in contact with the exposed portion of the bottom.

摘要： An electromagnetic relay includes an electromagnet block, a pair of fixed contacts, a movable spring, and a stopper. The electromagnet block includes an exciter coil and an armature. The movable spring includes a fixed portion and a movable portion. The fixed portion is fixed to the electromagnet block. The movable portion contacts fixed contact and is separated from the fixed contacts in response to turning on and off of an energizing of the exciter coil. The stopper configured to restrict a movement of the movable portion. The armature is fixed to the movable portion and is displaced unitarily with the movable portion. The movable spring is configured to, upon turning on the energizing of the exciter coil, cause the movable portion to move, by magnetic force, in an approaching direction in which the movable portion approaches the fixed contacts with the fixed portion functioning as a fulcrum, and contact the fixed connection portions. The movable spring is configured to, upon turning off the energizing of the exciter coil, cause the movable portion to be separated, by restoring force, from the fixed contacts in a separating direction in which the movable portion is separated from the fixed contacts. The stopper is configured to, upon turning on the energizing of the exciter coil, contact the movable portion and reduce a moving speed of the movable portion in the approaching direction before the movable portion contacts the fixed contacts. The stopper is configured to, upon turning off the energizing of the exciter coil, contact the armature and reduce the moving speed of the movable portion in the separating direction.
