Two-purpose light control switch for water flow and gas flow

The utility model relates to a two-purpose light control switch for water flows and air flows, which comprises a pipe body, a circuit board and a linking component. The utility model is characterized in that both axial ends of the pipe body are respectively provided with an inlet end pipe joint and an outlet end pipe joint. Both radical sides of a middle movable section are respectively provided with a tenon and a corresponding hole. The circuit board is oppositely arranged on both of the two radical sides of the movable section of the pipe body. A light control component on the circuit board corresponds to the corresponding holes, and a convex tenon hole arranged on one end of the light control component is correspondingly inlaid into the convex tenon of the pipe body. The linking component is composed of a movable valve, an elastic force component and a blade which are orderly connected in series. Both ends of the elastic component are sheathed with a convex block of the movable valve and a convex block of the blade and are contained into the pipe body. The movable valve is made from light material, and thus, the movable valve can be pushed by the force of the water flows and the air flows about 5g.
