Abstract
Implementations of the subject matter described herein provide a switching apparatus. The switching apparatus includes: a handle shaft coupled to a handle and arranged rotatable in a circumferential direction in response to an operation to the handle; and a locking plate arranged movable in a first direction in association with a rotation of the handle shaft. The handle shaft and the locking plate are operable to limit the rotation of the handle shaft when the handle shaft arrives at an off position of the switching apparatus.
