Abstract: An electromagnetic switch, including a driving apparatus and a contact apparatus. The contact apparatus includes a moving contact assembly, a chamber, and two spaced fixed contacts disposed on a top part of the chamber. The moving contact assembly includes an insulating part, a push rod, a moving contact, and an elastic part. One end of the push rod is mounted on the driving apparatus, and the other end of the push rod is mounted on the insulating part. The moving contact is mounted on one side that is of the insulating part and that is back to the push rod. The elastic part is clamped between the insulating part and the moving contact, so that the moving contact is in contact with or separated from the pair of fixed contacts under the action of the push rod.

Abstract: An energy storage status monitoring structure and a rotary switch are provided and relate to the field of electrical technologies. The energy storage status monitoring structure includes an operation mechanism, an energy storage assembly, and a release assembly. The operation mechanism includes an upper cover, a rotating shaft rotatably connected to the upper cover, and an energy storage tray connected to the rotating shaft. The energy storage assembly is connected to the energy storage tray. A sensing portion is disposed on the energy storage tray. A sensing component is disposed on the release assembly. When the energy storage tray rotates to enable the energy storage assembly to store energy, the sensing portion corresponds to the sensing component, so that the sensing component outputs a corresponding sensing signal.

Abstract: The application discloses a rotary switch, and relates to the field of electrical technologies. The rotary switch includes an operating mechanism, an on-off apparatus, and a tripping component, and the operating mechanism includes an energy storage component and a drive component. The drive component is separately in driving connection with the energy storage component and the on-off apparatus. The energy storage component includes a latch and an energy storage spring that cooperates with the latch. The energy storage spring can be separately connected to the latch and the drive component in a snap-fit manner, the drive component is rotated, so that the energy storage component can store energy, and the drive component is used to drive the on-off apparatus to be switched on. The latch cooperates with the tripping component, so that the latch locks or unlocks the energy storage spring.
