The Advance Touch Switch is the part of the CNG/LPG Electronic Circuit Unit and is installed in the vehicle dashboard near to
the driving seat.

 

How Switch Works: The car start (ignition), the orange light in ON indicating the car is on petrol, As we press accelerator (rpm increases), it automatically switches to the CNG as it reaches the set rpm(programmed i.e. 1200rpm) Greenlights become visible as the car is now running on CNG. The number of lights indicates the quantity of CNG available in the gas cylinder. Even if the CNG is still available in a gas cylinder and you want to switch into petrol, then just Touch the switch once. It will be switched to petrol. You will not feel any knocking during fuel conversions. End of CNG Indication When the red light becomes visible, it means that CNG is in its last phase. It will still run a few Km’s.
