Abstract: In this paper, we have discussed the Automotive Lever Combination switch, its mechanism, which is used in vehicles to control the electrical functions of the car - turn signals, headlight control, and wiper control; its common failures; and the contact-less systems. Previous research on contact-less technology on automotive lever combination switches was based on Hall-effect sensors. At the same time, we have explored the possibility of using an Optical Sensor to operate the Lever Light Switch. The experiment used an ESP32 board as the Main controller, TEMT6000 light sensors, LEDs, and an Automotive Lever Light Switch. The LED located bottom of the lever will be used by the optical sensor, which is incorporated inside the switch, to detect changes. It will convert the LED light into an electrical pulse, which the ESP32 will process. Once the signal interpretation has been completed in accordance with the logic defined in the ESP32 controller software, the results will be shown in the Verification Box.
