Abstract: An electromagnetic relay includes a contactor including a fixed contact and a movable contact, and an electromagnet device for moving the movable contact. The electromagnet device includes a coil generating a first magnetic flux by energization, a tubular body including a permanent magnet generating a second magnetic flux in a direction identical to a direction of the first magnetic flux and having a hollow extending in a center axis direction, a movable element disposed in the hollow of the tubular body and reciprocating in the center axis direction, and a yoke forming a magnetic circuit passing together with the movable element and the tubular body. The magnetic circuit allows at least one of the first and second magnetic fluxes to pass through the magnetic circuit. The electromagnet device is configured to, when the coil is energized, move the movable contact to a first position by attracting the movable element with the first magnetic flux and the second magnetic flux. The electromagnet device is configured to, when energization of the coil is suspended, move the movable contact to a second position different from the first position. This electromagnetic relay is easily designed and reduces power consumption at a low cost.

Abstract translation: 电磁继电器包括具有固定触点和可动触头的接触器，以及用于移动可动触头的电磁装置。 电磁体装置包括通过通电而产生第一磁通的线圈，包括永磁体的管状体，该永磁体在与第一磁通的方向相同的方向上产生第二磁通并具有沿中心轴方向延伸的中空， 设置在管状体的中空部并沿中心轴方向往复运动的可动元件，以及形成与可动元件和管状体一起通过的磁路的磁轭。 磁路允许第一和第二磁通中的至少一个通过磁路。 电磁体装置被构造成当线圈被通电时，通过用第一磁通和第二磁通量吸引可移动元件将可动触头移动到第一位置。 电磁体装置被构造成当线圈的通电被暂停时，将可动触头移动到与第一位置不同的第二位置。 该电磁继电器易于设计，并以低成本降低功耗。
