Patent ID: 8901445

Claim:
A magnetic contactor, comprising: a stationary contact including a first stationary contact piece having a stationary contact portion and a stationary terminal portion for connecting to a power supply, a second stationary contact piece having a stationary contact portion and a stationary terminal portion for connecting to a load, a third stationary contact piece disposed between the first stationary contact piece and the second stationary contact piece and having two stationary contact portions; a contact support casing supporting the stationary contact with the stationary terminal portions of the first stationary contact piece and the second stationary contact piece to protrude out of the contact support casing; a movable contact including a first movable contact piece contactable and separable from the stationary contact portion of the first stationary contact piece and one of the two stationary contact portions of the third stationary contact piece, a second movable contact piece contactable and separable from the stationary contact portion of the second stationary contact piece and the other stationary contact portion of the third stationary contact piece, and an insulator fixing the first movable contact piece and the second movable contact piece, the movable contact being installed in the contact support casing; a pair of arc extinguishing magnetic bodies arranged in parallel to sandwich the two stationary contact portions of the third stationary contact piece and the movable contact, and having some polarity at opposing magnetic pole faces; and a driving mechanism for driving the movable contact to contact with and separate from the stationary contact.
