Ventilation window for switch cabinet door
The invention relates to a ventilation window for a switch cabinet door. A window body is rectangular and is mounted with a frame on the periphery. A groove is formed in the frame. A magnet is arranged in the groove. A plurality of ventilation holes are sequentially distributed in the middle portion of the window body. The ventilation holes are round or oval or round and oval. The ventilation window is directly attracted to the switch cabinet door through the magnet and accordingly is easy to mount by omitting screws for fixing. Furthermore, the ventilation window for the switch cabinet door is simple in structure, low in machining cost, easy to disassemble and assemble and especially for use in an emergency situation that a worker can operate equipment in a switch cabinet without opening the cabinet door.
