Abstract:
1. An electromagnetic relay comprising: an electromagnet; an actuator which is actuated in response to a magnetic action of the electromagnet; a contact which opens and closes in response to the actuation of the actuator; and a housing for accommodating the electromagnet, the actuator and the contact, wherein the contact includes a movable spring having a base end fixed to a bottom of the housing and a tip end provided with a movable contact, and a fixed spring having a base end fixed to the bottom of the housing and a tip end provided with a fixed contact, the movable contact being provided opposite to the fixed contact and being moved in response to the actuation of the actuator, coming in contact with the fixed contact or moving away from the fixed contact, wherein the housing has a base and a cover with a top and sides, each side extending from the top of the cover to a base end in contact with the base, one side of the cover having a protrusion, disposed closer to the top of the cover than a midpoint between the base end and the top, protruding inward toward the fixed contact which is closer to the cover than the movable contact, and wherein the fixed spring includes a portion inclining relative to a protrusion side of the cover on which the protrusion is formed, thereby preventing the tip end of the fixed spring from touching the protrusion when the contact is open.
