The present invention provides a switch device whereby reduction of a mass of an actuator is effected and it is possible to implement a rapid acceleration operation, as well as to effect improved reliability. A switch device according to the present invention comprises: an interruption part formed from a fixed contact and a mobile contact which either contacts or separates from the fixed contact; a linear motor which generates drive force for the mobile contact to operate; and a thrust generation source which supplies additional thrust to the linear motor when the linear motor accelerates, decelerates, or accelerates and decelerates, in the contact or separation of the interruption part. |
