The invention relates to an intelligent controlling switch used for a local ventilating system. The intelligent controlling switch mainly aims at solving the problem that existing local ventilating systems can not satisfy the technical problems, including supplying air according to needs. The technical proposal comprises that the local ventilating system comprises an intelligent switch shell (11), an intelligent switch wiring box (12) and a switch body (14); the intelligent switch wiring box (12) is arranged on the intelligent switch shell (11); the intelligent switch wiring box (12) is provided with a cable introducing device (13); the switch body (14) is arranged in the intelligent switch shell (11); the switch body (14) is provided with a communicating module (9) and a programmable logic controller (PLC) (10); an intelligent switch operating handle (15) and a man-machine dialogue interface (7) are arranged on the intelligent switch shell (11) and are connected with the switch body (14); and the man-machine dialogue interface (7) is connected with the programmable logic controller (PLC) by a circuit. The intelligent controlling switch can realize close or remote intellectualized control to a local ventilator, thereby satisfying the requirements of the users to supply air according to needs. The intelligent controlling switch can be widely used in various local ventilating systems of mines.
