PROBLEM TO BE SOLVED: To provide an operation check device for a disconnector with improved detection accuracy of an opening and closing position of the disconnector by reducing an operating range of a magnetic proximity switch. SOLUTION: A turntable 8 is horizontally fixed to a lower part of a main shaft 2 of the disconnector 1, an opening magnetic terminal 9 and a closing magnetic terminal 10 are mounted on both ends of a bottom surface of the turntable 8, and an opening magnetic proximity switch 12 and a closing magnetic proximity switch 13 are mounted on a pedestal 3 using a mounting stay 11 at respective positions immediately below the opening magnetic terminal 9 and the closing magnetic terminal 10 in a state where the disconnector 1 is opened and closed. The opening magnetic terminal 9 is configured such that an operation check magnet and an interlock magnet are adjacent to a protection case, and an iron piece is mounted on rear parts of the operation check magnet and the interlock magnet, and these are sealed. The opening magnetic proximity switch 12 is configured such that an operation check switch and an interlock switch are adjacent to the protection case, and these are sealed.
