AI Technical Summary
The existing membrane switch requires disassembly of all components during repair, which damages components such as keycaps and scissor-mount brackets, resulting in low repair efficiency and high costs.
It adopts a stacked structure of keycaps, scissor-switch brackets, support plates, and function switches/membrane switches. The function switches/membrane switches are fixed to the lower surface of the support plate through a bonding process, achieving non-destructive separation and simplifying the maintenance process.
This technology enables the non-destructive and free separation of membrane switches, avoiding component damage, simplifying the maintenance process, and reducing maintenance costs.

Abstract
Claims
1. An input device capable of non-destructive free separation of membrane switch, comprising a key cap (1), a scissors leg support (2), a support plate (3), a function switch / membrane switch (4), characterized in that: The keycap (1) is a top operating component, and its bottom is adapted to the top of the scissor-foot bracket (2). The bottom of the scissor-foot bracket (2) is connected to the upper surface of the support plate (3). The lower surface of the support plate (3) is fitted with a function switch / membrane switch (4), forming a stacked structure from top to bottom consisting of keycap (1), scissor-foot bracket (2), support plate (3), and function switch / membrane switch (4).
2. An input device capable of non-destructive free separation of thin film switches as claimed in claim 1, characterized in that: The function switch / membrane switch (4) is fixed to the lower surface of the support plate (3) by bonding process. The bonding surface is a planar adaptation structure, so that the function switch / membrane switch (4) can be removed or replaced independently of the keycap (1) and scissor bracket (2).
3. An input device capable of non-destructive free separation of thin film switches as claimed in claim 1, wherein: The scissor-foot bracket (2) is a scissor-type mechanical support structure. Its upper end is engaged with the adapter slot / protrusion at the bottom of the keycap (1), and its lower end is engaged with the corresponding mounting position on the upper surface of the support plate (3). It is used to transmit pressing force and provide reset support force when the keycap (1) is pressed.
4. The input device for achieving non-destructive and free separation of membrane switches as described in claim 1, characterized in that: The support plate (3) is a rigid load-bearing component.
5. An input device capable of non-destructive free separation of thin film switches as claimed in claim 1, wherein: The function switch / membrane switch (4) has a built-in trigger circuit. When it is pressed by the support plate (3), the trigger circuit closes to generate an electrical signal, thereby realizing the signal triggering function of the input device.
