The structural assembly is simple and reliable. For the situation where multiple such switches are used on the panel, the structural cost and subsequent maintenance cost advantages are obvious.

[0035] Specifically, a protrusion 402 is provided on the elastic arm 401, and a plurality of vertically arranged openings 202 are provided on the fixed arm 201. The protrusion 402 can sequentially engage with the plurality of openings 202. Function: In the position retention mechanism implementation, when the button cap is pressed into place, the openings on the button cap engage with the protrusion 402 of the metal spring to achieve locking.

[0036] Specifically, the protrusion 402 is a semi-spherical protrusion, the opening 202 is a circular hole, and a transition opening 203 is provided between two adjacent openings 202. Function: In the implementation scheme of the position-retaining structure, the button cap and the metal spring (preferably made of SUS304) cooperate to achieve the position-retaining function. The metal spring and the button cap are designed to cooperate in a spring arm structure with a semi-spherical protrusion. The button cap is designed to cooperate in an opening. When the button cap is pressed into place, the opening on the button cap cooperates with the semi-spherical protrusion of the metal spring to achieve the locking action.

[0037] Specifically, the button 301 is a silicone button, the thickness of the metal spring 4 is 0.5mm±0.1mm, and the matching size of the raised structure 402 and the opening structure 202 is 1.5mm±0.3mm. Function: In the swing-torsion structure implementation scheme, the button cap is pressed and rotated at both ends by the rotating shaft, and the pressing action on the guide column causes it to slide up and down in the panel, thereby realizing the guide column pressing the silicone button to trigger the electronic function. Important parameters of structural components, in order to ensure the pressing feel and reliability of this structural scheme, the design considers the following two aspects: 1) The thickness of the metal spring is recommended to be 0.5mm±0.1mm to meet the requirements of the button cap matching retention force, while taking into account the feel when the button is pressed. 2) The matching size of the hemispherical raised structure of the metal spring and the button cap is recommended to be set to 1.5mm±0.3mm to ensure that the metal spring can provide the required retention force, so that the button cap will not loosen due to insufficient retention force of the metal spring when it is in the retained position.

[0038] Specifically, the through-opening 103 is L-shaped, with the elastic arm 401 located at the vertical opening of the through-opening 103, and the fixed arm 201 being able to downwardly pass through the horizontal opening of the through-opening 103. Function: The L-shaped opening not only allows for the installation of the elastic arm 401, but also enables a greater range of up and down swinging of the fixed arm 201.

[0039] Specifically, the sidewalls of the mounting groove 101 protrude downward, the front and rear sidewalls of the metal spring 4 bend upward and cover the front and rear outer walls of the mounting groove 101, and the elastic arm 401 protrudes toward the vertical opening through the opening 103. Purpose: This arrangement facilitates stable mating of the elastic arm 401 with the fixed arm 201.

[0040] Specifically, the bottom surface of panel 1 is provided with several screw posts 104 and several retaining slots 105. The metal spring 4 and PCBA assembly 3 are secured to the screw posts 104 of panel 1 via several screws 6. The front and rear sidewalls of the metal spring 4 are inserted upward into the retaining slots 105. This arrangement allows for better assembly and securement of the metal spring 4 and PCBA assembly 3.

[0041] Specifically, a plurality of through openings 103 are provided on the left and right sides of the front edge and the left and right sides of the rear edge of the assembly groove 101. A plurality of elastic arms 401 are provided on the left and right sides of the front edge and the left and right sides of the rear edge of the metal spring 4. A plurality of fixed arms 201 are provided on the left and right sides of the front edge and the left and right sides of the rear edge of the button cap 2. This arrangement ensures that the button cap 2 is subjected to a more balanced force in achieving the position-retaining structure.

[0042] Specifically, a rotation axis 106 is provided in the middle of the front and rear sidewalls of the assembly groove 101. A rotation hole 204 is provided in the middle of the front and rear sidewalls of the button cap 2. The front and rear rotation axes 106 rotatably engage with the rotation holes 204. A pressing block 205 is provided on the left and right sides of the bottom surface of the button cap 2, which presses down on the guide post 5. The rotation axis 106 allows the button cap to rotate while facilitating assembly. The pressing blocks 205 also facilitate the button cap's downward movement of the guide post.

[0043] Specifically, a rear housing 8 is located below the metal spring 4 and is screwed to the panel 1. A socket 7 is located below the PCBA assembly 3, extending downward through the metal spring 4 and rear housing 8. Function: Rear housing 8 protects the PCBA.
