Description

Technical Field

[0001] The invention relates to a rocking lever of an electric switch, a locking device having such a rocking lever and an electric switch having such a rocking lever or such a locking device. Background Art

[0002] An electrical circuit breaker may be equipped with a rocker lever, by which the electrical circuit breaker is actuated in order to switch on the current. A user of such a circuit breaker can lock the circuit breaker in different switch positions so that the circuit breaker cannot be actuated unintentionally. For example, it may be desirable to lock the circuit breaker in a closed position ("OFF"), in which the circuit is opened by the circuit breaker. Similarly, it may be desirable to lock the circuit breaker in an open position ("ON"), in which the circuit is closed by the electrical switch.

[0003] Document DE 10 2011 082 255 A1 discloses a locking device for an electromechanical switching device with manual actuation capability. The locking device is characterized by a combination of relatively few interlocking structural elements that are coordinated with each other in structure and function. The locking element has a dual function in that, on the one hand, the connection of the locking device to the switching device is ensured and, on the other hand, a position change of an operating element of the switching device is reliably prevented.

[0004] In other operating elements of the power switch, for example in the rotary drive, a design is also known, whereby the rotary drive can be locked by a U-lock. For example, this is known as an integrated solution, so that a part of the rotary handle is pressed inwards and is held in this position by the U-lock. The part of the rotary handle that is pressed inwards prevents it from being operated by the positioning plate. The rotary drive can be locked in the closed position ("OFF"). This design is also improved by subsequently drilling a hole in the positioning plate, so that the rotary drive can also be locked in the open position ("ON"). Summary of the invention
