Patent ID: 8477000

Claim:
A relay, comprising: a first relay main body including a first opening and closing part and a first magnetization driving part configured to cause the first opening and closing part to operate, the first opening and closing part including a first movable contact and a first fixed contact facing each other across a first gap so as to be movable into and out of contact with each other, a first movable terminal having the first movable contact, and a first fixed spring terminal having the first fixed contact; a second relay main body including a second opening and closing part and a second magnetization driving part configured to cause the second opening and closing part to operate, the second opening and closing part including a second movable contact and a second fixed contact facing each other across a second gap so as to be movable into and out of contact with each other, a second movable terminal having the second movable contact, and a second fixed terminal having the second fixed contact; a case that includes a first side plate part, a second side plate part facing toward the first side plate part, and a top plate part and covers the first relay main body and the second relay main body; and a first permanent magnet and a second permanent magnet fixed to the top plate part of the case so as to face the first gap and the second gap, respectively, the first permanent magnet and the second permanent magnet being oriented so as to have a same magnetic pole facing toward the first and second gaps, wherein the first permanent magnet and the second permanent magnet apply magnetic fields on the first gap and the second gap, respectively, to blow off a first arc generated in the first gap and a second arc generated in the second gap in opposite directions toward the first side plate part and the second side plate part, respectively.
