Change Over Switch Function

Change Over Switch is a key component in CNG and LPG vehicle systems, which helps in drivers to seamlessly switch between petrol and gas modes. It enables the vehicle to start on petrol and automatically shift to gas once the engine reaches the required temperature or conditions, it ensures smooth transitions and better fuel efficiency for vehicles . Our change over switches are compatible with major CNG sequential and conventional kits and suit a variety of vehicle types. The switch indicates which fuel is currently in use and often includes features like fuel level indicators, start-up mode selection (e.g., starting on petrol and switching to gas), and safety alerts. By enabling seamless transition between fuels, the change over switch helps improve fuel management, driving convenience, and vehicle performance in dual-fuel vehicles. They are built with robust and reliable electronics, they are easy to install, long-lasting, and highly responsive to real-time driving needs.Our change over switches are carefully selected and tested to ensure maximum performance, fuel efficiency, and safety for your vehicle.The change-over switch is a key part of the CNG/LPG electronic system, typically installed on the vehicle dashboard for easy access by the driver. This switch allows the driver to seamlessly transition between fuel types, such as from petrol to CNG or LPG.

Change over switches are widely used in dual-fuel vehicles that run on both CNG or LPG and petrol, allowing drivers to easily switch between the two fuel sources. These switches are typically installed on the dashboard and are used in passenger cars, taxis, buses, and commercial vehicles. They enable manual or automatic switching based on fuel availability or engine conditions, ensuring continuous operation even if one fuel runs out. In some systems, the vehicle starts on petrol and automatically switches to CNG or LPG once the engine warms up, enhancing performance and safety. Change over switches are also used in retrofit kits for converting petrol vehicles to CNG or LPG.

Change over switches offer several advantages in CNG and LPG dual-fuel systems. They provide fuel flexibility, allowing drivers to switch between petrol and gas based on availability or cost, helping reduce fuel expenses. These switches enhance convenience by enabling easy, often automatic, transitions between fuels without interrupting engine performance. They also support engine protection, as some systems allow the engine to start on petrol and switch to gas once the ideal temperature is reached, reducing wear. Additionally, change over switches often include fuel level indicators and warning lights, improving fuel management and safety
