A rotary isolator switch includes a plurality of switch units and a drive mechanism that are sequentially arranged. Each switch unit includes a moving contact component. The drive mechanism drives the moving contact component to rotate. A switch unit that is farthest away from the drive mechanism includes an isolation cover plate. The isolation cover plate includes an observation hole and a reference mark, so that a rotation angle of a second moving contact component can be visualized, and a connection status of the rotary isolator switch can be determined based on a position of the second moving contact component. The reference mark is located on a peripheral side of the observation hole. A pointer is disposed on a side that is of the second moving contact component and that faces the isolation cover plate.

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.

An isolation switch includes a plurality of posts connectable to trace lines and/or a ground line at one side of a housing of the switch. Inside the switch, a conducting contact plate can be moved between a bonded mode, where each of the terminals are interconnected, and a test mode, where the contact plate moves, within the housing, electrically isolating each post and allowing for discrete locating.
