Abstract

The invention discloses a key and a mobile terminal therewith. The key comprises at least one pressing part, at least one dome array, a circuit board and an insulating blanket, wherein the dome array is disposed between the circuit board and the insulating blanket. Projection portions with the number the same as that of the dome array are arranged on the insulating blanket, and each projection portion is positioned in a place corresponding to the center of the dome array. The mobile terminal comprises the key mentioned above. With the use of the key and the mobile terminal, pressing feelings the key brings can be well improved, misuse is reduced, and key failure can be effectively avoided.

Description

technical field [0001] The invention relates to a button and a mobile terminal including the same. Background technique [0002] DOME sheet, that is, metal dome array / Dome Array, taking the most common DOME sheet as an example, it is a thin sheet containing metal domes, and each metal dome is arranged according to the corresponding pad position on the circuit board position, and other components to set the corresponding evacuation positions and positioning holes. DOME sheets are used as switches on circuit boards such as PCB (printed circuit board) or flexible circuit board (ie FPC), and play an important role as a tactile switch between the user and the instrument. Compared with traditional silicone keys, DOME sheets have a better feel and longer life, and can also indirectly improve the production efficiency of various types of switches using conductive films. The working principle of the DOME chip is that the metal shrapnel is located on the conductive part of the circu...
