A mounting structure for an energy storage assembly of a circuit breaker comprises an energy storage lever and an energy storage spring, wherein one end of the energy storage lever is an energy storage end which is connected with the energy storage spring, and the other end of the energy storage lever is a driving end. An external force can be applied to the driving end, such that the energy storage lever rotates around a lever fulcrum in the middle of the energy storage lever, thereby extruding the energy storage spring at the energy storage end to finish energy storage. One end of the energy storage spring is connected and mounted with the energy storage lever, and the other end of the energy storage spring is mounted in a base support. An energy storage mounting shaft which can be considered as a rotating fulcrum is also arranged in the middle of the energy storage lever. The driving end is stressed, such that the energy storage lever rotates around the energy storage mounting shaft. The mounting structure for the energy storage assembly of the circuit breaker, which is provided by the present invention, is simple in mounting process, stable in connection structure and high in assembly accuracy.

A key structure includes a base plate, a keycap and a connecting element. The connecting element includes a first frame and a second frame. The first frame is connected with the base plate and the keycap. The first frame includes a first linking part. The second frame is connected with the base plate and the keycap. The second frame includes a second linking part. The second linking part is contacted with the first linking part. When a depressing force from the user is applied to the keycap, the first frame is swung relative to the second frame. Moreover, in response to a friction between the first linking part and the second linking part, the keycap is correspondingly moved.
