Abstract

The utility model discloses a switch structure. The switch structure comprises a base, a press member, a torsion spring and a casing, wherein the press member and the torsion spring are accommodated in the base; an axle post and a plurality of conductive sheets are arranged on the inner wall of the base; a joint hole capable of movably pivoting with the axle post is formed on the press member; an embedded post body is formed outwards at the outer periphery of the joint hole; a sheath section of the torsion spring is sheathed and located on the embedded post body in such a way that a first contact section and a second contact section extending outwards from both sides of the sheath section respectively butt against two conductive sheets to form electric conduction; and the casing covers the base. When being pushed, a pull section on the press member can make rotation displacement around the axle post so as to drive the second contact section on the torsion spring to be disconnected from the conductive sheet and to butt against the inner wall of the base in a sliding manner, thereby forming electric disconnection and achieving on-off operation of the switch. The torsion spring with good elastic torsion function can be used as an elastic sheet, which can enhance the butting contact stability.
