Abstract
An electromagnetic contactor includes a contact mechanism including a pair of fixed contacts having fixed contact portions and interposed in a current conduction path, and a movable contact having a pair of movable contact portions capable of contacting to and separating from the pair of fixed contact portions. At least one of the pair of fixed contacts or the movable contact is formed in a shape to form magnetic fields generating Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and the movable contact portions when current is conducted. External connection conductors are connected to external connection terminals of the fixed contacts, an attachment direction of fixed portions fixed to the external connection terminal of the fixed contacts is set to cross a current flow direction flowing through the movable contact.
