Summary:The present disclosure relates to a switch valve unit (4), a fluid switch (1), and a fluid switch assembly. The switch valve unit comprises a valve seat (5) which defines a valve cavity (51) having an open bottom end port (514); an at least partially axially deformable diaphragm member (7) which is mounted in the valve cavity to divide the valve cavity into an upper cavity portion (510) and a lower cavity portion (512), and provided with a first hole (710) and a second hole (712) spaced from each other and providing fluid communication between the upper cavity portion and the lower cavity portion; a button (6) axially movably mounted on the valve seat; and a valve rod assembly (8) connected to the button so as to follow the movement of the button, extending through the valve seat (5) and into the upper cavity portion, and having a first position to seal the first hole and a second position to depart from the second first hole.
