<p>PROBLEM TO BE SOLVED: To provide an electromagnetic relay capable of improving the heat dissipation efficiency when the power is supplied to an exciting coil.SOLUTION: An electromagnet unit 2 moves a movable element 22 by attracting the movable element 22 to a stator 23 when a magnetic flux generated by an exciting coil 21 is applied to a yoke 24 which is disposed enclosing the exciting coil 21. A contact unit 3 is arranged to switch between a close state in which a movable contact 32 comes into contact with a fixed contact 31 and an open state in which the movable contact 32 is separated from the fixed contact 31 by when the movable contact 32 is moved accompanying the movement of the movable element 22. A case 4 stores at least the electromagnet unit 2. An intervention member 5 which has the thermal conductivity higher than the air is disposed in a space 6 between the yoke 24 and the case 4.</p> |
