Patent ID: 8853585

Claim:
An electromagnetic contactor comprising: a first stationary contact having a stationary contact portion and a stationary terminal portion for connecting to a power supply; a second stationary contact having a stationary contact portion and a stationary terminal portion for connecting to a load; a stationary-contact supporting case supporting the first stationary contact and the second stationary contact, the stationary terminal portion of the first stationary contact and the stationary terminal portion of the second stationary contact protruding out of the stationary-contact supporting case and maintaining a predetermined distance inbetween; a moving-contact portion arranged in the stationary-contact supporting case, and contactable to and separable from the stationary contact portion of the first stationary contact and the stationary contact portion of the second stationary contact; a pair of arc-extinguishing magnets arranged in parallel to sandwich the moving-contact portion in a direction orthogonal to a longitudinal direction of the moving-contact portion, and having same magnetic polarity at opposing magnetic pole surfaces thereof; and a driving mechanism for driving the moving-contact portion to contact with and separate from the stationary contact portion of the first stationary contact and the stationary contact portion of the second stationary contact, wherein the pair of arc-extinguishing magnets each is disposed on a side surface of the stationary-contact supporting case between the first stationary contact and the second stationary contact.
