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.

Cradle-assist assemblies attached to the breaker cradle housing and/or base or residing at least partially in the breaker cradle housing and/or base include at least one actuator configured to laterally translate the at least one right and the at least one left lock members from the extended lock position to the retracted unlocked position in response to input from a user. The at least one actuator and/or transverse member(s) can be held in a defined position so that the lock members of the cradle can be locked in the respective retracted or extended positions until the cradle assist (internal) lock is manually or automatically released.

To prevent incoincidence of contacts, a safety switch switches the contacts by cooperation of an actuator and a switch body. The switch body includes an operating cam and a locking cam that rotate due to insertion of the actuator, an operating rod that switches the contact according to rotation of the operating cam, and a locking lever that is movable toward and away from the locking cam such that the locking lever takes a lock position in which it locks rotation of the locking cam and an unlock position in which it unlocks rotation of the locking cam. The locking lever includes a bulge protruding toward the locking cam. A cam contact surface of the locking lever contacts the locking cam when the actuator moves in a drawing-out direction in an intermediate position between the lock position and the unlock position.

A locking mechanism for a circuit breaker operation device includes a housing (1). A button (2) is mounted in a button slot (101) of the housing (1). The locking mechanism is characterized in that the housing (1) is provided with a locking member (3) therein, and the locking member (3) can lock or unlock the button (2). In the locking mechanism for a circuit breaker operation device, a locking member is added in the circuit breaker; only after a lock button is pressed, an operation button is pressed to close the circuit breaker; when the operation button is pulled out, the circuit breaker is disconnected; when the lock button is not pressed, the operation button is locked by the lock button, the operation button cannot be pressed down, the circuit breaker cannot be closed.
