The invention discloses a combined brake valve with an automatic pressure switch. The combined brake valve comprises a valve body, a brake piston, an air valve and the automatic pressure switch, the air valve is used for controlling the communication state of a brake air channel, the brake piston can vertically move in a valve cavity of the valve body and is used for providing starting power for the air valve, a driving chamber for providing driving air pressure is formed above the brake piston, a buffer chamber is formed below the brake piston, and the automatic pressure switch is connected with the buffer chamber. When inputted air pressure is low, inputted compressed air is conveyed into the buffer chamber by the automatic pressure switch to counteract part of lower push force for driving the indoor driving air pressure for the brake piston. When the inputted air pressure is high, the air in the buffer chamber is discharged by the automatic pressure switch. The brake air pressure and releasing speed can be adjusted as needed by the added automatic pressure switch, tires cannot be locked when no-load brake is performed, rapidness and effectiveness are ensured when load brake is performed, running safety of vehicles is greatly improved, and braking damage to the tires is reduced.
