Description

Technical Field

[0001] This utility model relates to the field of tactile switch technology, and specifically to a tactile switch with good stability. Background Technology

[0002] A tactile switch is an electronic switch that typically turns a circuit on or off by gently pressing its operating lever. Inside a tactile switch is usually a flexible metal plate or conductive rubber. When an external force is applied to the switch's operating lever, the metal plate or rubber deforms and makes contact with the contacts, thus turning on the circuit. When the external force is removed, the switch returns to its initial state due to its internal elastic restoring force, and the circuit is turned off.

[0003] However, because existing tactile switches do not have a structure to guide the operating lever, they are prone to misalignment when the operating lever is pressed. This can lead to uneven stress and deformation of the metal plate after prolonged use. Furthermore, the operating lever is reset only by the elasticity of the metal plate, resulting in a small reset force. This can cause the operating lever to fail to reset, resulting in the metal plate not being able to spring back perfectly, thus leading to low stability of the tactile switch.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stable tactile switch includes a base, an operating handle, a metal sheet, a cover plate, and a guide rod. The base has an internal cavity, and the metal sheet is located in the center of the cavity. The metal sheet has a centrally arched structure. The bottom of the operating handle has a pressure block that contacts the central arch of the metal sheet. One lead-out foot is provided on one side of the base, and another lead-out foot is provided on the other side of the base. One contact point is provided on both sides of the cavity, and each contact point is connected to the first lead-out foot. A second contact point is provided in the center of the cavity, and the second contact point is connected to the second lead-out foot. The bottom end of the guide rod is connected to the bottom wall of the cavity. Through holes are provided on both sides of the metal sheet, and the top end of the guide rod passes through the through holes and connects to the bottom wall of the operating handle.

[0008] Preferably, the guide rod includes a telescopic rod one, a telescopic rod two is movably connected inside the telescopic rod one, the telescopic rod one is provided with an elastic element inside, the telescopic rod one is connected to the bottom wall of the accommodating cavity, and the telescopic rod two is connected to the bottom wall of the operating handle.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the tactile switches with good stability provided in this embodiment of the utility model have at least one of the following technical effects:

[0013] This utility model, through the above-mentioned technical solution, guides the operating handle with a guide rod, preventing the operating handle from shifting when pressed. This avoids the problem of deformation of the metal piece caused by the operating handle shifting during pressing.

[0021] like Figure 1-2 The diagram shown is a structural schematic of a tactile switch with good stability according to a preferred embodiment of the present invention.

[0022] In this embodiment, the system includes a base 1, an operating handle 2, a metal sheet 3, a cover plate 4, and a guide rod 5. The base 1 has an internal cavity 6. The metal sheet 3 is located in the center of the cavity 6 and has a centrally arched structure. A pressure block 7 is located at the bottom of the operating handle 2, and the pressure block 7 contacts the centrally arched part of the metal sheet 3. Pressing the operating handle 2 causes the pressure block 7 to press down on the metal sheet 3, resulting in deformation. One side of the base 1 has a lead-out foot 8, and the other side has a lead-out foot 9. Contact points 10 are located on both sides of the cavity 6, and each contact point 10 is connected to the lead-out foot 8. A contact point 11 is located in the center of the cavity 6. Contact point 11 is connected to lead-out pin 9. Lead-out pin 8 and lead-out pin 9 connect the tactile switch to the outside world. The bottom end of the guide rod 5 is connected to the bottom wall of the accommodating cavity 6. Both sides of the metal sheet 3 have through holes 12. The top end of the guide rod 5 passes through the through holes 12 and connects to the bottom wall of the operating handle 2. The guide rod 5 can guide the operating handle 2 to avoid deviation when the operating handle 2 is pressed, thereby avoiding the problem of deformation of the metal sheet 3 caused by the deviation of the operating handle 2. Furthermore, the guide rod 5 pushes the operating handle 2 upward to reset, avoiding the problem of the operating handle 2 failing to reset and the metal sheet 3 failing to spring back perfectly, thereby effectively improving the stability of the tactile switch.

[0023] In this embodiment, the guide rod 5 includes a telescopic rod 13, and a telescopic rod 2 14 is movably connected inside the telescopic rod 13. An elastic element 15 is provided inside the telescopic rod 13. The telescopic rod 13 is connected to the bottom wall of the accommodating cavity 6, and the telescopic rod 2 14 is connected to the bottom wall of the operating handle 2. This structure realizes the telescopic function of the guide rod 5.

[0024] In this embodiment, the elastic element 15 is a spring. The two ends of the elastic element 15 abut against the first telescopic rod 13 and the second telescopic rod 14 respectively. The elastic element 15 increases the elastic force between the first telescopic rod 13 and the second telescopic rod 14, so that the guide rod 5 has sufficient elastic force to push the operating handle 2 to reset.

[0025] In this embodiment, the edge of the metal sheet 3 contacts the contact point 10, and this structure realizes the connection between the metal sheet 3 and the lead-out pin 8.

[0026] The present invention provides a tactile switch with good stability. Its installation method, connection method or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.
