Using the sensor can be used for the power MOS FET power switch, the switch can be used photoresistor LDR. When light is irradiated onto the photosensitive resistor, LDR low resistance, a signal is applied to the gate of the field effect transistor off, the source and drain between conduction from the surface of the relay coil K changes state, for generating control signals, or, if connected to the photoresistor LDR at the low potential, in the dark when no light is irradiated onto the photosensitive resistor, with the photosensitive resistor. Light control switch circuit diagram shown in Fig.
