Abstract

The invention discloses a key structure and a portable mobile terminal, relating to the technical field of electronics. The invention solves the technical problem of larger size of the inside diameter of a through hole in the traditional key structure. The key structure comprises a key cap, a through hole, a rubber cushion and a key switch, wherein the through hole is arranged on a casing; the rubber cushion is fixedly provided with a pressing protrusion; the key switch is opposite to the pressing protrusion, the through hole and the key cap; the key cap is made from elastic materials, and is arranged on a port of the through hole far away from the key switch; and the pressure is applied to the key cap at one side of the key cap far away from the key switch in a direction close to the key switch, the pressure can make the key cap deformed along the axial direction of the through hole, and the pressing protrusion is driven by the deformed key cap to press the key switch. The portable mobile terminal comprises a casing, a circuit board and the key structure disclosed in the invention, and the key structure is a key structure of an on-hook key and / or a key structure of a dialing key.
