    Arm-drive Earthing Switch Operating Interlocking Divice

    This interlock device increases reverse interlock of the backdoor based on 5XS .363.010. After
    the backdoor(seal plate) is closed, the earthing switch can be operated.
    The working principle of this interlock device is that when the backdoor (seal plate) is closed,
    the lock sleeve enters the cabinet square hole to relieve interlock with the support, so that the
    earthing switch can be operated.
    When the earthing switch is closed and the backdoor is open, the pin shaft can be reset by
    spring force, and stretch out to lock the operating shaft, in order to prevent the earthing switch from
    breaking.
    Structural advantage: This interlock device has the same function as 5XS.363.010.1, so users
    don't need to change any size of the cabinet for direct exchange with the holes of original
    5XS.363.010, and only change original operating shaft and lock sleeve into the four components
    shown in the figure to realize anti-lock function of backdoor. This interlock device has better
    reliability, strength, convenient maintenance and replacement than 5XS.363.010.1.
    When the backdoor is opened, this pin shaft stretches out and the operating shaft is locked.
    When the backdoor is closed, this pin shaft retracts and the operating shaft is unlocked.
