MAGNETIC SWITCH

A magnetic switch includes: a housing 210; a cylinder 260 coupled to an inner side of the housing 210; a stationary contact arm 220 coupled to the housing 210; a movable contact arm 250 positioned to be movable within the housing 210 and brought into contact with the stationary contact arm or separated therefrom; a coil assembly 230 installed within the housing 210 and configured to form a magnetic field when a current is applied thereto; a movable shaft 241 coupled to the movable contact arm 250 in an upper portion thereof; a fixed core 243 inserted into the cylinder 260 and surrounding the movable shaft 241; and movable cores 245-1 and 245-2 fixed to the movable shaft 241 and configured to press the movable shaft 241 by a magnetic field formed by the coil assembly 230 to move the movable shaft, wherein the movable cores 245-1 and 240-2 include protrusion portions 246a and 246b extending toward the movable shaft 241 and fixed to the movable shaft 241 and body portions 246a and 246b configured to move in contact with an inner diameter of the cylinder 260, and the fixed core 243 has an accommodation portion 244 for accommodating the protrusion portions 246a and 246b. The movable cores 245-1 and 245-2 include protrusions 246a and 246b, the fixed core 243 includes the accommodation portion 244, and as the protrusions 246a and 246b of the movable cores 245-1 and 245-2 move within the accommodation portion 244 of the fixed core 243, a maximum compression distance of the contact spring 281 increases and short-circuit performance of the magnetic switch can be enhanced.
