Beschreibung
Zusammenfassung:	The invention relates to a lamp tube switching device, which comprises a shell, a switching circuit which is arranged in the shell, a sliding arm which is pivoted on the shell, and at least two contact sets which are arranged on the surface of the shell. The sliding arm comprises three conductive bulges which face to the shell, wherein the three conductive bulges are connected between a power supply and switch elements which are arranged in the switching circuit. The at least two contact sets are connected with the switch elements and are in a one-to-one corresponding relationship with lamp tube types. When the sliding arm is rotated to the position of the contact set corresponding to one lamp tube type, the conductive bulge on the sliding arm is in electric contact with the contact set, the corresponding switch element is conducted, a lamp tube connecting end which is arranged in the switching circuit is connected with the power supply to form a conducting circuit corresponding to the lamp tube type and lamp
