A switch device for a gas burner includes a body engaged with a housing. The body defines an axial hole for rotatably receiving a driven shaft which has a first end secured in a rotation knob and a second end engaged with a barrel which can be rotated by the driven shaft. The barrel is screwed in the housing which is connected to a primary flame nozzle. When the rotation knob is pressed, the valve rod mounted in the barrel is forced by driven shaft to move linearly so as to open the valve hole directed toward the auxiliary flame. When the rotation knob is rotated, the passage directed toward the primary flame nozzle is opened.
