Junction box and lighting switch

The invention relates to the technical field of electrical equipment, and discloses a junction box and a lighting switch. The junction box comprises a mounting base and door bodies, a threading groove is formed in the mounting base, the two door bodies are rotationally arranged in the threading groove respectively, a notch of the threading groove can be blocked by closing the two door bodies, the notch of the threading groove can be opened by rotating the two door bodies, and a connecting part is arranged on each door body and used for being fixedly connected with the switch panel through a fastener. When the switch panel is not installed, the two door bodies are closed to block the notch of the threading groove of the installation seat, the pre-embedded electric wire is prevented from being exposed, the electric shock accident of personnel is avoided, the safety performance of the junction box is improved, when the switch panel needs to be installed, the two door bodies are rotated to open the notch of the t
