Abstract
A power switch circuit includes a switch circuit, a solar photovoltaic panel and a detection circuit and connected with the solar photovoltaic panel and the switch circuit respectively. The solar photovoltaic panel is configured to provide an electrical signal to the detection circuit, the detection circuit is configured to detect whether the power in the electric signal exceeds a preset threshold, and when the power exceeds the preset threshold, the detection circuit outputs a first control signal to the switch circuit to turn on the switch circuit; when the switch circuit is turned on, the solar photovoltaic panel supplies power to the load through the switch circuit, and the switch circuit feeds back a second control signal to the detection circuit so that the detection circuit stops working.
