Abstract
An electromagnetic contactor includes 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 section for connecting to a load; a stationary-contact supporting case supporting the stationary terminal portions of the first and second stationary contacts to protrude the contact support casing, and maintaining a predetermined distance in between; a moving-contact portion contactable to and separable from the stationary contact portion of the first and second stationary contact and arranged in the stationary-contact supporting case; and a pair of arc-extinguishing magnets arranged in parallel to sandwich the moving-contact portion in the longitudinal direction and having same magnetic polarity at opposing magnetic pole surfaces. A driving mechanism drives the moving-contact portion contactable to and separable from the stationary contact portions of the first and second stationary contacts.
