POWER SWITCH CIRCUIT AND POWER SWITCH

The present application provides a power switch circuit and a power switch. The power switch circuit includes a solar photovoltaic panel, a detection circuit and a switch circuit, wherein the detection circuit is 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. By detecting the power of the solar photovoltaic panel in the above way, the waste of power energy caused by the solar photovoltaic panel being started too early or too late can be avoided, and when the solar photovoltaic panel supplies power to the load, the detection circuit is controlled to stop working, thereby improving the power generation capacity and utilization rate of the solar photovoltaic panel.
