HOWO A7 T7H Dual Fuel Tank Selector Switch WG9925582011
Core Functions
1. Control of Fuel Circuit Switching (Solenoid Valve Actuation): Pressing or toggling the switch sends a 24V electrical signal to the fuel three-way solenoid valve located on the chassis. This activates the solenoid valve's internal spool, enabling precise switching between the supply and return fuel lines of the main and auxiliary tanks.
2. Synchronized Fuel Gauge Display Switching (Sensor Interfacing): This is a multi-contact composite switch. As it switches the fuel circuit, internal electronic contacts simultaneously connect the dashboard fuel gauge signal line to the fuel level sender (sensor) of the corresponding tank. Result: When switched to the main tank, the dashboard displays the fuel level for the main tank; when switched to the auxiliary tank, the gauge seamlessly updates to show the real-time fuel level of the auxiliary tank.
