The electromagnetic switch device 100 provided by the present invention has a simple structure, simple parts processing and assembly, and low cost.
具体地，位于线圈1轴向一侧的磁钢组件2的充磁方向与位于线圈1轴向另一侧的磁钢组件2的充磁方向相反，形成穿过线圈1的磁场，线圈1的两侧均位于S极与N极之间。Specifically, the magnetizing direction of the magnetic steel component 2 located on the axial side of the coil 1 is opposite to the magnetizing direction of the magnetic steel component 2 located on the other axial side of the coil 1 to form a magnetic field passing through the coil 1. Both sides are located between the S pole and the N pole.
