Abstract
An electromagnetic contactor according to the present invention is so constructed that the electromagnetic device and the fixed point of contact are fixedly fitted into a casing which is divisible in the direction along the moving direction of a polar contact. Moreover, a bottom casing with a screw mounting hole is fitted in the outer peripheral portion at the lower end of the casing. Therefore, the rigidity of the casing as a whole is enhanced, and at the same time the working characteristics can be prevented from being changed when the screw is mounted. Furthermore, the positioning accuracy of the electromagnetic device relative to the fixed point of contact is determined only by the dimensional accuracy of the casing and the electromagnetic device, and by the position accuracy of the fixed point of contact. The contact pressure is improved to be stable.
