Abstract

An electromagnetic relay comprising: a contact case, a pair of fixed terminals each having a pair of fixed contact parts, a movable contact having a pair of movable contact parts respectively opposed to the pair of fixed contact parts, The cover portion of the through hole can be opened and closed. And it is configured that when the pair of movable contact parts is in contact with the pair of fixed contact parts, the cover part linked with the movable contact opens the through hole, and on the other hand, the pair of movable contact parts In the separated state where the dot part is separated from the pair of fixed contact parts, the cover part interlocking with the movable contact closes the through hole.

Description

technical field [0001] The present invention relates to electromagnetic relays. Background technique [0002] Patent Document 1 discloses an electromagnetic relay comprising: a case having a storage portion inside, a pair of fixed terminals each fixed to the case and having a fixed contact portion, and a pair of fixed terminals arranged so as to be contactable with respect to each fixed contact portion. A pair of movable contact portions separated from each other and a movable contact movable in a contact-separation direction in which each movable contact portion contacts or separates from a corresponding fixed contact portion. In this electromagnetic relay, there is provided a ventilating passage which communicates between the storage portion and the outside of the casing, and through the ventilating passage, the arc gas of the arc generated when each movable contact portion comes into contact with or separates from the corresponding fixed contact portion is discharged to t...
