The utility model relates to a ring network switch having a phase checking function. A structure of the ring network switch is that a terminal of the ring network switch is connected with an electrified display I and an electrified display II, nuclear phase terminal ports of the electrified display I and the electrified display II are connected with a voltage determining and monitoring module, and an output terminal of the voltage determining and monitoring module is connected with an opening and closing locking coil of the ring network switch. The ring network switch is high in reliability, detects three phases of a circuit by sensors of the electrified displays, has obvious directivity and high sensitivity and is safe and reliable. Cost is reduced, the monitoring module directly determines sensor detection signals, operation personnel do not need to do on-site experiments, so that manpower and material resource cost is reduced. Operation is simple and convenient, security is high, anti-interference ability
