When closed, the handle is just placed on the upper end of the transparent cover, which limits the flip of the transparent cover, and the padlock hole is designed on the handle to add a padlock, so as to ensure the personal safety of users ( Only break off the load first, and then split the switch "effectively cut off" the DC isolator, to open the transparent open cover and the components and switches in the transparent cover). Clear marks are provided at the opening and closing locations for easy operation;
