Abstract

An electromagnetic switch device is disclosed. The electromagnetic switch device includes: a case; a fixed contact inside the case; a movable contact positioned below the fixed contact to repeatedly perform contact with and separation from the fixed contact; a shaft, It is coupled with a movable contact; a return spring, which continuously pushes down on the shaft; and a movable iron core, which is coupled with the shaft. The shaft includes a pressing surface directed downward, and the movable core is arranged to be in contact with an upper end of the pressing surface so that if the movable core and the shaft move upward, the movable core presses the pressing surface The pressing surface is moved upward so that if the movable iron core and the shaft move downward, the pressing surface pushes the movable iron core downward to push the movable iron core downward.

Description

technical field [0001] This embodiment relates to an electromagnetic switch device. More specifically, the present embodiment relates to an electromagnetic switch device capable of improving durability by improving the structure of the actuating portion. Background technique [0002] An electromagnetic switchgear is an electric switchgear used to connect a converter to switch on / off a main circuit according to a small change in input current. In electromagnetic switching devices, the contacts are moved by electromagnetic force so that current is applied or interrupted. [0003] figure 1 is a cross-sectional view showing a part of an electromagnetic switch device according to the related art. [0004] The fixed iron core 5 and the movable iron core 7 having a hollow structure are vertically disposed in the yoke 4 while being spaced apart from each other, and are opposed to each other by a return spring 8 interposed between the fixed iron core 5 and the movable iron core 7 ...
