To reduce an operation force of a movable contactor together with contact resistance among a fixed-side electrode, a movable-side electrode and movable contactors.
A disconnecting device includes: a fixed-side electrode 1 forming one electric circuit; a movable-side electrode 2 forming the other electric circuit; and movable contactors 3a, 3b which are rotated using an operation shaft provided in the movable-side electrode 2 as a supporting point and come into contact with or separate from the fixed-side electrode 1. On a contact/separate surface through which the movable contactors 3a, 3b come into contact with or separate from the fixed-side electrode 1 and a sliding surface through which the movable contactors 3a, 3b slide with the movable-side electrode 2, rotation contact members are provided which have rotation contactors 10a, 10b, and pressure springs 11a, 11b applying contact load thereto.
