ELECTROMAGNETIC SWITCH DEVICE

Provided is an electromagnetic switch device configured so that impact force generated between a plunger and a stator core when the plunger makes contact with the stator core can be reduced. This electromagnetic switch device is provided with: a stator core; a plunger moving between a contact position and a separated position; an attraction coil for generating, by means of an electric current supplied thereto, a magnetic field for moving the plunger from the separated position toward the contact position; a retention coil for generating, by means of an electric current supplied thereto, both a magnetic field for moving the plunger from the separated position toward the contact position, and a magnetic field for maintaining the position of the plunger at the contact position. The retention coil is disposed offset relative to the contact surface of the stator core in the direction of movement of the plunger. 一种电磁开关装置，能够使柱塞与固定铁芯接触时在柱塞与固定铁芯之间产生的冲击力降低。该电磁开关装置包括：固定铁芯；柱塞，柱塞在接触位置与分离位置之间移动；吸引线圈，通过被供给电流，吸引线圈产生使柱塞从分离位置向
