Fuel Selection and Status Indication for Gas Conversion
This CNG signal indicator switch provides manual fuel selection and operating-mode indication in a compatible conversion system. It is intended for cabin installation and must be matched to the vehicle wiring and gas-control arrangement.
The switch selects between petrol and the configured gas fuel. Indicator meanings and output functions depend on the supplied version. Confirm the wiring diagram before connecting valves, gauges or other control components.

What Functions Does the Switch Provide?
Fuel selection: Manual selection of the configured petrol or gas operating mode.
Status indication: Indicator lights display the selected mode according to the version-specific operating instructions.
Control outputs: Electrical outputs operate compatible components according to the wiring diagram.
Gauge interface: Connection to a matching external gauge or sensor arrangement where supported.
Operating current and output-load current are separate specifications. The current consumed by the switch does not define the allowable current of a connected solenoid valve. Match each load to its documented output limit.
Compatibility Checks Before Ordering
Connector shape alone does not establish compatibility. Match the terminal functions, power requirements and control logic to the existing system.
Provide the switch model or identification marking.
Send clear photographs of the connector and existing wiring.
Identify the fuel and whether the system uses a carburetor, EFI mixer or sequential injection.
Specify connected valve loads and any required relays.
Provide the external gauge or sensor model and signal specification.
EFI mixer and sequential injection applications require separate confirmation. Do not assume that a carburetor-system switch can replace an ECU-specific control panel. Browse our autogas ECU products when identifying the associated controller.

Frequently Asked Questions
Can this switch work with both CNG and LPG?
The supplied version must match the intended fuel system. Confirm the wiring, gauge characteristics and control functions separately for an LPG application. A similar appearance does not establish interchangeability.
Does the switch measure gas pressure directly?
Any pressure-related indication depends on a compatible external gauge or sensor. Confirm the sensor supply, signal range and indication characteristics. The switch is not a pressure regulator.
Can it drive a solenoid valve directly?
Direct connection depends on the documented output specification. Check the valve current, switching arrangement and any relay requirements before wiring. Do not infer the output capacity from the switch's operating current.
What information is needed for a replacement order?
The existing switch identification and wiring details are the most useful starting points. Include connector photographs, terminal markings, system type and the connected gauge or sensor model.
What are the MOQ and warranty period?
The minimum order quantity is 50 pieces, with an 18-month warranty period. Confirm the applicable coverage, exclusions and claim procedure in the sales terms.
Installation and Functional Checks
Installation must follow the version-specific wiring instructions. A qualified installer should verify polarity, circuit protection, terminal assignments and load compatibility before energizing the switch.
Commissioning should verify the complete fuel-selection sequence. Check mode selection, indicator behavior, connected outputs and the required shutdown response. Electrical control alone does not establish that a gas valve seals correctly.
Related components must be selected as part of the complete system. Read our conversion kit component guide for the roles of the controller, valves, reducer and other parts.
