Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the present application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., "fixed" may be fixedly connected or detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in the figure, a mechanical type contact change over switch, it is including setting up driving lever guide way and slide 2 on moulded case circuit breaker upper cover 1, the slide surface extends and forms driving lever 6, is equipped with manual and automatic sign respectively in the left and right sides of driving lever 6 simultaneously for directly perceivedly understand moulded case circuit breaker current state, driving lever 6 passes driving lever guide way sets up and can follow driving lever guide way length direction slides, the one end of slide is equipped with bump 9, the upper cover inboard is equipped with concave point 13, the driving lever has when being located driving lever guide way 12 one end and triggering the primary importance that sets up micro-gap switch 7 in the moulded case circuit breaker casing and being located the driving lever guide way other end the convex point constitutes mechanical interlocking's second place with the concave point.

The distance between the deflector rod and the salient point 9 is less than or equal to the length of the deflector rod guide groove, namely, when the manual mode is adopted, the salient point is limited by one end of the deflector rod guide groove, and the mechanical interlocking effect is realized.

The slide perpendicular slip direction forms baffle 3, and when the driving lever is in the second position, the manual operation spare that moulded case circuit breaker was sheltered from to the baffle, and this manual operation spare is interior hexagonal axle, shelters from through the baffle and avoids outside personnel to carry out manual operation.
