The invention relates to a multifunctional switching electromagnetic valve. A valve body is included; a first valve cavity, a second valve cavity and a third valve cavity are sequentially arranged inthe valve body from top to bottom; a first channel communicating the first valve cavity with the second valve cavity is formed in the valve body; a second channel communicating the second valve cavitywith the third valve cavity is formed in the valve body; the valve body is provided with a first gas outlet, a first exhausting port, a gas inlet, a second exhausting port and a second gas outlet; the first gas outlet is communicated with the first valve cavity; the first exhausting port, the gas inlet and the second exhausting port are all communicated with the second valve cavity; the second gas outlet is communicated with the third valve cavity; a first valve rod is movably arranged in the first valve cavity; a second valve rod is movably arranged in the second valve cavity; and a third valve rod is movably arranged in the third valve cavity. The multifunctional switching electromagnetic valve is simple and reasonable in structure, small in occupied space, attractive in appearance andcapable of being used in different occasions.
