  • Patent number: 11170959
    Abstract: An electromagnetic relay includes a base having a receiving space, an electromagnetic unit disposed outside of the receiving space, a magnetically attractive member magnetically attractable by the electromagnet unit, a first stationary contact disposed in the receiving space, a second stationary contact, a movable terminal member and a movable contact. When the electromagnetic unit is energized, the movable terminal member is pushed by the magnetically attractive member and the movable contact contacts one of the first and second stationary contacts. When the electromagnetic unit is de-energized, the movable contact contacts the other one of the first and second stationary contacts.

  • Patent number: 11087942
    Abstract: An electromagnetic relay includes a base, an electromagnet disposed on the base, an armature unit having a magnetically attractive member magnetically attractable by the electromagnet, a movable terminal unit mounted on the armature unit and including a first terminal member and a first contact, and a stationary terminal member mounted on the base. The first terminal member is a two-piece structure composed of a spring plate and a first leg. A ratio of the thickness of the first leg to the thickness of the spring plate ranges from 2 to 4. When the electromagnet is energized and de-energized, the first contact contacts and moves away from the second contact, respectively. A method of making the electromagnetic relay is also disclosed.
