Introduction:
    The interlocking device has improved reverse blocking of the backdoor on the basis of the original interlocking device of 5VACY.363.010.4 earthing switch operating mechanism. When the backdoor is open(sealed plate), the original interlocking can still operate earthing switch, and this interlock can not be operated, the backdoor(sealed plate) should be closed before operation of the earthing switch.
    The working principle of this interlocking device is that it changes the back support and put it in the middle to achieve the reverse blocking based on the original 5VACY.363.010.4. When the backdoor (sealed plate) is opened, connecting plate welding moves outwards of the cabinet under the force of pressure spring , the interlocking screw is rotated to the lower part of the cabinet by holding the rotating block and is locked in the groove under the rotating block to achieve locking, and the earthing switch can not be operated.

Characteristic:
1. Do not need consider the salty distance from the back
2. Easy installation
3. Flexible, simple and reliable
