交通信号機用工事時電源切替器。 A power supply switch that switches between a regular power source and a standby power source, which includes a line changeover switch that switches the power line connected to the load line within 10 msec by switching the manual switching section, a regular power supply connection terminal, and a line changeover switch. During construction for a traffic signal, the construction is characterized by comprising a regular power switch interposed between the two, and an out-of-phase alarm circuit connected between the primary side of the regular power switch and the secondary side of the track changeover switch. Power switch.
