description The utility model discloses a switch cabinet door control switch circuit based on dual protection, comprising a rectification filtering module which is connected with a power supply part; the door opening detection module is connected with the rectifying and filtering module; the trigger module is connected with the door opening detection module, a photoresistor and an indicating lamp are connected in series in the trigger module, and the resistance value of the photoresistor can switch on or switch off a current signal of an indicating lamp loop; the technical application range is relatively wide, and on one hand, the mis-tripping of equipment caused by the mis-induction phenomenon of a contact after the high-voltage switch cabinet door runs for a long time is effectively avoided; secondly, based on the characteristics of the photoresistor, the cabinet door is opened by mistake when power is not cut off, the resistance value of the photoresistor is directly reduced due to light irradiation, a protection trip
