Abstract:
1. An electromagnetic contact device comprising, a case accommodating an electromagnet having a movable core for attraction movement and release movement; a movable contact point support moving between an initial position and an operation position in parallel with a moving direction of the movable core; a return spring urging said movable contact point support toward the initial position; and a driving lever engaging the movable core and the movable contact point support, and transmitting the attraction movement of the movable core to the movable contact point support as a moving force toward the operation position, wherein a lever holding portion is formed in an inner wall of an extinction cover, and by mounting said extinction cover on the case and having the lever holding portion to axially support one end of the driving lever, the driving lever is accommodated such that another end thereof engaged with the movable core and movable contact point support rotates with the one end as a rotation support point; and when the movable contact point support stops midway during release, the release movement from the inertial force of the movable core is transmitted to the movable contact point support through the driving lever as a moving force toward the initial position.
