Abstract:
An electromagnetic relay includes multiple contact sets each including a fixed contact and a movable contact displaceable in a first direction to approach the fixed contact and in a second direction to move away from the fixed contact; multiple permanent magnets each provided on the peripheral side of a corresponding one of the contact sets and having a polarity direction perpendicular to the first and second directions; and multiple ferromagnetic bodies parallel to the polarity directions of the permanent magnets and the first and second directions, wherein in a DC electric current flowing through each of the contact sets, the direction of a force exerted based on the permanent magnet is equal to the direction of a force exerted based on the ferromagnetic body.
