The proximity delay switch 9 can automatically turn off after a certain period of time without manual shutdown, which can save energy.

[0034] Working principle:

[0035] When maintenance is required on the top of the car, the user will enter the top of the car through the opening of the car top guardrail body 1. When a person passes through the opening of the car top guardrail body 1, the proximity delay switch 9 will detect the person, thus forming a closed circuit with the mains power, the proximity delay switch 9 and the indicator light 10, thereby illuminating the indicator light 10 to indicate the location of the main switch 7 for the worker to turn on. Due to the inherent characteristics of the proximity delay switch 9, it will automatically disconnect after a certain period of time when no object is approaching, thus turning off the indicator light 10 and avoiding energy waste.

[0036] By turning on the main switch 7, the bus 6 is connected, thus forming a circuit with the mains power, bus 6, main switch 7, wire 3, lamp holder 2 and LED light source 5, so that the LED light source 5 emits light, making it convenient for users to maintain the top of the car.
