- the operation plate 70 engaged with is in the return position. Therefore, the open / close and energization movable contacts 57 and 58 are separated from the open / close and energization fixed contacts 31 and 32. At this time, the facing distance between the open / close fixed contact 31 and the open / close movable contact 57 is shorter than the facing distance between the energizing fixed contact 32 and the energizing movable contact 58.
- the operating arm portion 65 of the rotated rotating operation body 60 slides the operation plate 70, and the inner side surface of the engagement slit 73 of the operation plate 70 is the bent pieces 51 g and 51 g of the first movable contact piece 51. Press simultaneously.
- the movable contact 57 for opening and closing and the movable contact 58 for energization rotate around the portion fixed to the movable contact terminal 40 by caulking.
- the tall open / close movable contact 57 first contacts the open / close fixed contact 31 (FIG. 16B)
- the energizing movable contact 58 contacts the energizing fixed contact 32.
- the operation plate 70 pushes the bent piece 51 g of the movable contact piece unit 50. For this reason, the open / close movable contact 57 and the energizing movable contact 58 are brought into pressure contact with the open / close fixed contact 31 and the energizing fixed contact 32 at a predetermined contact pressure, respectively. Next, even if the application of voltage to the coil 22 is stopped, the rotating operation body 60 maintains the state by the magnetic force of the permanent magnet.
- the rotating operation body 60 rotates in the reverse direction, so that the operating arm portion 65 causes the operating plate 70 to move the operating plate 70.
- the engagement arm portion 72 of the operation plate 70 pulls back the free end portion of the movable contact piece unit 50 and returns to the original position.
- the consumable powder generated by the generation of the arc does not adhere to the energizing fixed contact 32 and the energizing movable contact 58, and the contact resistance does not increase, and an electromagnetic relay that hardly generates heat is obtained.
- the electromagnetic relay according to the present invention is not limited to the above-described electromagnetic relay, but may be applied to other electromagnetic relays and electrical devices.
