ち、電磁継電器の動作音が低減する。"Prior Art" Figure 2 is a partial cross-sectional view of an electromagnetic relay according to the prior art, in which 1 is a board, 2 is a case, 3 is an iron core, 4 is a coil, 5 is a yoke, 6 is an armature, and 7 is a movable spring. , 8 are dampers, and 9 and 10 are fixed contact terminals. Next, the operation will be described. First, under normal conditions, the movable terminal 7a provided at the tip of the movable spring 7 is brought into contact with the fixed contact 10a provided at the tip of the fixed contact terminal 10. Next, when the coil 4 is energized and the armature 6 is attracted by the armature 6, the movable contact 7a comes into contact with the fixed contact 9a, but a damper 8 is interposed between the armature 6 and the iron core 3. Therefore, the collision speed between the armature 6 and the iron core 3 is reduced, and the operating noise of the electromagnetic relay is reduced.
