Abstract
Provided is an electromagnetic contactor (20) which transmits an attraction movement of a movable core (8d) of an electromagnet (8), via a drive lever (9), to a movable contact support (7a) that is movable in parallel with the movable core (8d), wherein an urging portion (21) for applying an urging force to the movable core (8d) is provided such that the movable core (8d) is held at a movable core initial position which is apart from a fixed core (8c) and does not allow engagement with the movable contact support (7a).
Claims5
An electromagnetic contactor, accommodating, in a case,
- an electromagnet having a movable core performing an attraction movement by a generation of an attraction force between the movable core and a fixed core,
- a movable contact support moving between an initial position and a contact switching position in parallel with a movement direction of the movable core,
- a return spring urging the movable contact support toward the initial position, and
- a drive lever engaging the movable core and the movable contact support, and transmitting the attraction movement of the movable core with respect to the movable contact support as a movement toward the switching position,
- wherein the electromagnetic contactor includes an urging portion applying an urging force to the movable core to hold the movable core at the movable core initial position, which is apart from the fixed core and does not engage the movable contact support.
