ABSTRACT:
A relay includes a contact point block having a support shaft with both ends spanning a contact point base, a plunger having a movable contact at a lower end thereof, and a movable iron piece configured to drive the plunger and to have a plate spring. The relay also includes an electromagnetic unit and a base block having a fixed contact point at a position opposite to the movable contact point. The movable iron piece is supported on the supporting shaft. The plunger is inserted through an operation hole of the contact point base. Upper and lower surfaces of the contact point block are held by the electromagnetic unit and the base block. The electromagnetic unit directly fixes the iron core to an upper surface of the contact point base.
