Background
An electronic switch is required in some consumer electronics products (such as mobile phones, cameras, camcorders, notebook computers or PADs, etc.), electronic communications, electronic instruments, industrial controls, medical devices, automotive industry, smart toys, and household appliances.
The existing common switch is a conventional plastic key or a silica gel key, a metal elastic sheet, a PCB (printed Circuit Board) or an FPC (Flexible printed Circuit) circuit board or a light touch switch, wherein most of the used metal keys have lower stroke and higher hand feeling, and a user cannot conveniently feed back the keys well (the stroke is low and the sound is loud).
Disclosure of Invention
The utility model provides a switch module group with low hand feeling and high travel, which is novel in structure, when a user presses a key panel on the contact surface, the built-in salient point is pressed, so that the metal elastic sheet starts to deform downwards, and when the deformation reaches the maximum deformation of the metal elastic sheet structure, the switch module group can instantly contact a circuit layer below the metal elastic part to form a conduction loop to achieve the switching effect; the invention can effectively improve the pressing stroke by arranging the built-in salient points, and ensure the hand feeling when the pressing is conducted; in addition, the metal elastic sheet is pressed to be conducted with the circuit layer in the pressing process, so that the switch module can be pressed to be in contact with a conventional product with less sound, and the structure is reliable.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a switch module of high stroke is felt to low, including keypad, cover lamella, metal elasticity portion and lamella between, keypad sets up on covering the lamella, the lamella sets up the bottom at the cover lamella between, the upper end middle part of metal elasticity portion is provided with built-in bump, the up end of built-in bump with the lower extreme middle part of covering the lamella is connected, cover the lamella with lamella vacuole formation between, metal elasticity portion with built-in bump all is located in the cavity.
Wherein, the metal elastic part is a metal elastic sheet.
Wherein, the metal elastic part is arranged in a cross shape.
The interlayer layer is arranged in an annular shape, and the hollow part in the middle of the interlayer layer and the covering sheet layer form the cavity.
Wherein, the interlayer layer is made of insulating materials.
The utility model has the advantages that:
the utility model has novel structure and ingenious design, the key panel can be a plastic or silica gel key, the covering layer is used for fixing the position of the interlayer layer and the metal elastic part, and the interlayer layer plays an insulating role; when a user presses the key panel on the contact surface, the built-in salient points are pressed, so that the metal elastic sheet starts to deform downwards, and when the deformation reaches the maximum deformation of the metal elastic sheet structure, the built-in salient points can instantly contact the circuit layer below the metal elastic part to form a conduction loop to achieve the switching effect; the invention can effectively improve the pressing stroke by arranging the built-in salient points, and ensure the hand feeling when the pressing is conducted; in addition, the metal elastic sheet is pressed to be conducted with the circuit layer in the pressing process, so that the switch module can be pressed to be in contact with a conventional product with less sound, and the structure is reliable.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
A switch module with low hand feeling and high travel is shown in figure 1 and comprises a key panel, a cover sheet layer 1, a metal elastic part 2 and a middle sheet layer 3, wherein the key panel is arranged on the cover sheet layer 1, the middle sheet layer 3 is arranged at the bottom of the cover sheet layer 1, a built-in bump 4 is arranged in the middle of the upper end of the metal elastic part 2, the upper end face of the built-in bump 4 is connected with the middle of the lower end of the cover sheet layer 1, the cover sheet layer 1 and the middle sheet layer 3 form a cavity 5, and the metal elastic part 2 and the built-in bump 4 are both located in the cavity 5. The metal elastic part 2 is a metal elastic sheet, and the interlayer 3 is made of an insulating material. Specifically, the utility model has novel structure and ingenious design, the key panel can be a plastic or silica gel key, the covering layer is used for fixing the positions of the interlayer layer 3 and the metal elastic part 2, and the interlayer layer 3 plays an insulating role; when a user presses the key panel on the contact surface, the built-in salient points 4 are pressed, so that the metal elastic sheet starts to deform downwards, and when the deformation reaches the maximum deformation of the metal elastic sheet structure, the metal elastic sheet structure instantaneously contacts the circuit layer 100 below the metal elastic part 2 to form a conduction loop to achieve the switching action; the embodiment can effectively improve the pressing stroke by arranging the built-in salient points 4, and ensure the hand feeling when the pressing is conducted; in addition, in the pressing process, the metal elastic sheet is pressed to be conducted with the circuit layer 100, so that the switch module can be pressed to contact with a circuit board with less sound and has a reliable structure compared with a conventional product.
