Abstract

The present invention relates to a magnetic switch, and more particularly, a magnetic switch capable of preventing degradation of breaking efficiency by utilizing magnetic force to the utmost, in a manner of matching contact centers of fixed and movable cores. A magnetic switch according to one embodiment includes a bobbin provided with a cylindrical body and a plurality of flanges and having a coil wound on an outer circumferential surface thereof, a fixed core fixed to an inside of the cylindrical body with a predetermined spaced interval from the cylindrical body, and a movable core slidably installed in the cylindrical body and contactable with or separated from the fixed core, wherein a guide portion protrudes from a lower portion of the cylindrical body along an inner circumferential surface of the cylindrical body, such that the movable core can linearly move along a central axis of the fixed core.
