The structure of the manual lock is relatively simple, usually without complex electronic components or mechanical devices. This means it has a lower failure rate because there aren't as many parts that can fail.
From a production point of view, the manually locked latch device does not require complex automation equipment and high-end electronic components in the manufacturing process, so the cost is relatively low.
The biggest advantage of automatic locking is convenience. When you close the system door, the latch drops automatically without additional manual operation.
The automatic lock device is usually more elaborate and hidden in the internal structure of the door, and does not appear on the surface of the door as obtrusive as the manual latch. This helps to enhance the overall aesthetics of the system door, making it more in line with the aesthetic requirements of modern homes and buildings.
