Electrical control cabinets can be found everywhere. Workers should check, operate and adjust at any time. In addition to the maintenance state, the cabinet door must be closed and completely locked. At this time, the manual button for closing the door must be pressed to ensure that the cabinet door will not be opened by mistake. Not to mention that in the operating state, the manual button for closing the door must be in the pressed state.

Safety is no small matter! Should not leave any security risks!
