Abstract

An electromagnetic relay includes: a yoke (10) capable of changing a magnetic pole thereof by an electromagnet (20); an armature (12) that is magnetized by a permanent magnet and contacts with or separates from the yoke (10) in accordance with the magnetic pole of the yoke; a movable contact (30) that contacts with a fixing contact (40); an elastic body (32) that biases the movable contact (30); and a pressing member (16) that presses the elastic body (32) in accordance with a movement of the armature (12) to cause the movable contact (30) to at least contact with or separate from the fixing contact (40), wherein a cover (13) fixing the permanent magnet and the armature (12), and the pressing member (16) are integrally formed.

Description

technical field [0001] Certain aspects of the embodiments discussed herein relate to an electromagnetic relay. Background technique [0002] Japanese Patent Application Laid-Open No. 2001-126601 (hereinafter, described as Patent Document 1) discloses an electromagnetic relay including: a yoke capable of changing its magnetic pole by an electromagnet; The armature is magnetized by a permanent magnet. The magnetic pole of the yoke is changed by changing the polarity of the electromagnet. This causes the armature to come into contact with the yoke or to separate from the yoke. The elastic body biases the movable contact, and the pressing member presses the elastic body according to the movement of the armature. This causes the fixed contact and the movable contact to come into contact with each other or to separate from each other. The function as an electromagnetic relay is realized as described above. [0003] However, the member that transmits the movement of the armatu...
