Embodiment Construction

[0065] Next, the subsequent specific preferred embodiments and additional technical requirements will be described one by one.

[0066] Unless otherwise stated, the following embodiments are set so that the guiding direction a is perpendicular to the horizontal plane of the casing.

[0067] See Figure 6 It is a side sectional view of the button of the second embodiment.

[0068] The second embodiment also has the structure of the front cover 3, and the button 1 covered with the front cover 3 has a guide column 12 perpendicular to the horizontal plane of the housing 2 and a linear slide that cooperates with the guide hole 23 that is opened downward on the top surface of the vertical housing 2. The guide device of mechanism adopts the guide post 12 of rectangular cross section, to avoid friction and collision with the hole wall of the keyhole 30 of button 1 rotating left and right with front cover 3; The convex portion 35 of the side wall of the key hole 30 is resisted from a...

Abstract

The invention discloses a press key provided with a guiding device, which is installed on a shell body with a curved surface (including a plane) while the shell body is provided with switch contact points and circuits. A springing device is further arranged and a front cover is integrated with the shell body as a whole body if the front cover is available. The press key with the structure of the invention has simple structure, low cost, convenient and high-efficiency installation, portable operation, and stability and durability, and provides waterproof and dustproof functions for circuits in equipment, and has ultra-thin press key with a comparatively large stroke. Furthermore, the press key of the invention does not occupy the resources of a PCB board in the equipment, can be installed on the shell boy with the curved surface (including the plane) in low cost, and is applicable to the press keys and touch switches of electronic equipment with large, middle and small strokes.

Description

Technical field: [0001] The invention relates to an ultra-thin key switch device which is suitable for large, medium and small strokes, can be installed on surfaces of various shapes, and provides waterproof and dustproof functions for equipment, and is suitable for key switches and light touch switches of electronic equipment. Background technique: [0002] see figure 1 , 2 The side sectional structural diagram of the existing button, the existing button 1 relies on the cooperative positioning between the key body 11 and the key hole 30 (through hole) of the front cover 3, when the button 1 is pressed, the push button 10 at the bottom of the button 1 Push the movable contact 40 to move and touch the fixed contact 41 set on the substrate 2 to realize switch triggering. After the external force is released, the elastic device 5 rebounds to make the button 1 return to its normal state, thus completing a switching process. [0003] In this switching process, the existing key ...
