Claims3
An electromagnetic contactor comprising a case accommodating:
- an electromagnet having a movable core;
- a movable contact support moving in parallel with a moving direction of the movable core;
- and
- a drive lever which has directivity in assembly in the case, one end portion engaged with the movable core, and a central portion in a longitudinal direction engaged with the movable contact support, wherein the drive lever made rotatable about the other end portion thereof serving as a rotation axis transmits a movement of the movable core to the movable contact support by engaging the other end portion of the drive lever to an inner wall of a cover attached to the case covering the movable contact support, and
- a drive lever incorrect assembly detection portion is provided in which in a state where the drive lever is assembled in a correct direction, the driver is accommodated to attach the cover on the case, and in a state in which the drive lever is assembled in an incorrect direction, the other end portion of the drive lever protrudes to a position where the cover is attached to the case to prevent the attachment of the cover to the case.
