[0002] At present, most of the entrances and exits of special-purpose vehicles are two-door, and the control circuit realizes the requirements of lighting control by adding relays. However, with the continuous development of technology, the degree of integration and informatization is constantly improving, and special-purpose vehicles have more functions to ensure their practicality and comfort. With the integration of functions, the length of the special-purpose vehicle will also become longer, and the number of equipment on the vehicle will also increase. In order to facilitate the use of the whole vehicle, the number of entrances and exits will also increase. The commonly used control circuit will become more complicated, and the use of relays will increase. Summary of the invention

[0005] Preferably, the output end of the lighting switch is connected to the common end of the mode conversion switch, the normal mode output end of the mode conversion switch is connected to the live end of the lighting lamp, and the live ends of all the lighting lamps are connected in parallel; the neutral ends of all the lighting lamps are connected in parallel and then connected to the neutral end N of the power input;

[0006] The air defense mode output terminal of the mode conversion switch is connected to the normally open contact input terminal of the first travel switch, the normally open contact output terminal of the first travel switch is connected to the normally open contact input terminal of the second travel switch... and so on, the normally open contact output terminal of the n-1th travel switch is connected to the normally open contact input terminal of the nth travel switch, and the normally open contact output terminal of the nth travel switch is connected to the live wire terminal of the lighting lamp.
