Switching circuit

The utility model relates to the technical field of electric switch products, and provides a switching circuit. The switching circuit comprises a switch element, a rectification unit, a divider resistor, a direct-current power supply unit and an indicating unit. The rectification unit is coupled with an external alternating-current power supply system and used for converting an input alternating-current power supply into a direct-current power supply. The switch element is connected between the rectification unit and an electrical appliance in series. The divider resistor is coupled with the rectification unit. The direct-current power supply unit is in serial connection with the indicating unit, and then is parallelly connected to two ends of the divider resistor through the switch element. When the external alternating-current power supply system stops supplying power and the switch element is closed, the direct-current power supply unit supplies power to the indicating unit so as to enable the indicating u
