The invention provides an electromagnetic contactor which can prevent the poor operation or contact, caused by abrasion powder generated in a housing, of a change-over switch. The interior of the electromagnetic contactor is provided with the change-over switch (18) in a buried manner. In the change-over switch (18), an external rotable part (38) passing through an external opening window (40) from a switch box (29) bulges to the outside. A movable supporting part (22) is provided with a switching buckling part (28) which can be buckled with the external rotable part (38). Furthermore, a gap surrounding the external rotable part (38) rotating in the external opening window (40) is sealed through a dustproof part (42). |
