JSN(W)1 type anti misoperation mechanical program lockDetailed product description：

JSN (W) 1 series anti misoperation mechanical program lock is a specialized mechanical lock for high-voltage switchgear. This lock forces operators to operate electrical equipment according to established safety operating procedures, thereby avoiding misoperation of electrical equipment and meeting the "five prevention" requirements relatively comprehensively. This product is equipped with a master key that can open any lock for non programmed operations such as live work after the equipment is shipped, debugged, or put into operation.

The JSN (W) 1 anti misoperation mechanical program lock has the ability to distinguish between the opening and closing positions of each knife switch and the opening and closing position of the mesh door. And during operation, there is no need to switch keys one by one. Only one key is needed to complete multiple operations in a circuit according to the specified program. Due to the absence of a pin in the lock, it overcomes the inherent drawbacks of pin locks. This is a breakthrough and pioneering in China.
