To provide a disconnecting switch which suppresses displacement of a return spring.
The disconnecting switch comprises: a contact part 2 having a fixed contact 22 and a movable contact 21; a shaft 3 which moves the movable contact 21 to and away from the fixed contact 22; an operation lever 51 which moves the shaft 3 forward and backward between a closing position where the movable contact 21 contacts the fixed contact 22 and an opening position where the movable contact 21 leaves the fixed contact 22; a restriction part 8 which restricts movements of the operation lever 51; and a unit body 1. The restriction part 8 includes a lock button 81 which is operated to release the operation lever 51 from being restricted; a restriction body 83 provided to the lock button 81 in one body, and arranged to move forward and backward between a restriction position for restricting the movements of the operation lever 51 and a release position for removing the restriction; and a return spring 82 which applies spring force to the restriction body 83 toward the restriction position. Further, the unit body 1 is provided with ribs 15 and 15 suppressing displacement of an end of the return spring 82.
