Abstract

Implementations of the subject matter described herein provide a switching apparatus. The switching apparatus includes: a switching component including a first main shaft, which is adapted to selectively connect and disconnect at least one circuit in response to the rotation of the first main shaft; and an operating mechanism including a second main shaft for actuating the first main shaft to rotate via the second main shaft; wherein the switching component further includes a first interface, and the operating mechanism further includes a second interface, and the second main shaft to be detachably coupled to the first main shaft in response to the engagement of the first interface and the second interface.

Dependent claims

A switching apparatus comprising:

a switching component comprising a first main shaft and adapted to selectively connect or disconnect at least one circuit in response to a rotation of the first main shaft;
and
an operating mechanism comprising a second main shaft for actuating the rotation of the first main shaft;
wherein the switching component comprises a first interface, the operating mechanism comprises a second interface, and the second main shaft can be detachably coupled to the first main shaft in response to an engagement of the first interface and the second interface, wherein the switching apparatus further comprises a locking member arranged inside the first interface for locking the first main shaft in at least two rotation positions each corresponding to a switching state of the switching component,
wherein the first main shaft comprises at least one locking slot arranged on a circumference, and the locking member comprises a locking pin operable to be inserted into one of the at least one locking slot to limit the rotation of the first main shaft.
