1. A flow control switch, comprising:
a pipeline structure including a tubular body and a ball body rotatably disposed in the tubular body;
a rotating structure including a rotatable element connected to the ball body for driving the ball body to rotate relative to the tubular body;
a position-limiting structure disposed on the tubular body to surround the rotatable element; and
a knob structure liftably disposed on the rotating structure for cooperating with the rotatable element;
wherein the position-limiting structure has a first position-limiting groove, a second position-limiting groove adjacent to the first position-limiting groove, and a third position-limiting groove adjacent to the second position-limiting groove and corresponding to the first position-limiting groove;
wherein the knob structure includes a knob body liftably disposed on the rotatable element and a position-limiting element detachably disposed on the knob body, and the position-limiting element of the knob structure is optionally disposed in one of the first position-limiting groove, the second position-limiting groove and the third position-limiting groove, so as to limit a rotation of the rotatable element relative to the position-limiting structure.
