Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.

The complexity here is that we need to fix the circuit in a mobile and remote place—the helmet. So, simplifying the circuit is most important to make it compact and reliable. The circuit diagram is ...

In our case, the only thing you need to know is that we power the ICL8038 module with 12V to ensure a higher frequency output. In the above circuit diagram, you can clearly see the complete layout.
