PROBLEM TO BE SOLVED: To provide a switching device wherein foreign matters such as lubricating oil or the like from infiltrating into a case housing a stationary contact and a movable contact, the movable contact can be brought into contact with or separated from the stationary contact, and also, the movable contact can be more speedily brought into contact with and separated from the stationary contact to improve switch performance. SOLUTION: The magnetic attraction of a magnet 5 which reaches a movable contact 6 in a sealed case 1 through yokes 3, 4 changes due to movement of a magnetic short-circuiting body 16 by movement of a moving element 13 outside the sealing case 1. Accordingly, the magnetic short-circuiting body moves the movable contact 6 to a stationary contact 10 without going into the sealed case 1 to be detachably brought into contact with the stationary contact 10.
