Zusammenfassung: | The utility model discloses a street light automatic timing control box including a changeover switch, a light control switch, a control relay set, a manual control circuit and a timing circuit. An output end of the control relay set is connected to a null line (N) of an AC power supply, and an input end of the control relay set is connected to an output end of a normally-open contact of the light control switch (LX). An input end of the normally-open contact of the light control switch (LX) is connected to a first output end (2) of the changeover switch (ST). An input end (1) of the changeover switch (ST) is connected to a live wire (L) of the AC power supply. An input end of the manual control circuit is connected to a second output end (3) of the changeover switch (ST), and an output end of the manual control circuit is connected to an input end of the control relay set. The timing circuit is formed by connection of a work coil of a relay (KV) to a control loop of a timer (KT). According to the utility mod |
