Claims

[Claims for Utility Model Registration] (1) One end side of a contact spring is fixed, a movable contact is supported in the middle of the contact spring, and the contact spring is driven by an electromagnetic device so that the movable contact becomes a fixed contact. The electromagnetic relay is configured such that the movable contact is opened and separated from the fixed contact by the contact spring, and the electromagnetic relay is provided with a contact surface that restricts movement of the contact spring, and the movable contact is connected to the fixed contact. An electromagnetic relay characterized in that the contact spring contacts the contact surface before contacting the contact. (2) If the contact spring is divided into two halves, and one of the spring pieces faces a position closer to the driving part of the electromagnet device than the other spring piece, and when the electromagnet device is driven, first the said driving part The contact contacts the spring piece on the near side and then the spring piece on the far side, and then the movable contact comes into contact with the fixed contact after the spring piece on the far side hits the contact surface. An electromagnetic relay according to claim 1 of the utility model registration claim. (3) When the electromagnet device is not driven, the spring piece on the near side is in contact with another surface, and when the electromagnet device is driven, the driving part first hits the spring piece on the near side, The electromagnetic relay according to claim 2, wherein the spring piece on the near side is separated from the other contact surface, and then the driving section also hits the spring piece on the far side. (4) Another surface is another fixed contact, and the spring piece on the near side closes to the other fixed contact when the electromagnet device is not being driven, thereby driving the electromagnet device. The electromagnetic relay according to claim 3, which carries another movable contact that is sometimes separated from the other fixed contact.
