AI Technical Summary
When the existing switch trips unexpectedly, the rotation position of the operating handle is not obvious, which leads to misjudgment by the operator.
A switch opening and closing mechanism was designed, including a sliding plate, a limit frame, and an elastic telescopic component. The sliding plate slides between the closed and open positions. The compression and release of the elastic telescopic component drives the operating handle to rotate significantly, ensuring a significant change in position.
This effectively avoids operators misjudging the switch status, ensures accurate judgment of the operating handle in the closed and open positions, and prevents damage to the switch and operating handle.
