The rotatable cover 2 has a first setting part 22 and a second setting part 23 configured corresponding to the bottom plate 11. The inner side of the rotatable cover 2 has an inner top wall 24 and two protruding columns 25 protruding from the inner top wall 24. A receiving hole 241 is provided on the inner top wall 24.

[0058] Specifically described as follows, the first setting part 22 and the second setting part 23 respectively have a concave hole 251 opened at the bottom of each protruding column 25. Each concave hole 251 is divided into a blind hole section 252 and a tapered hole section 253. Each tapered hole section 253 gradually increases in diameter from the blind hole section 252 towards the direction close to the bottom plate 11.

[0059] As Figure 1 、Figures 3 to 6 As shown, the connecting mechanism 3 includes an annular groove 31 formed in one of the fixed base 1 and the rotatable cover 2, and a plurality of elastic arms 32 extending from the other of the fixed base 1 and the rotatable cover 2. The plurality of elastic arms 32 are slidably engaged with the annular groove 31 along the circumferential and axial directions of the annular groove 31, so that the rotatable cover 2 can be rotatably and liftably connected above the fixed base 1 relative to the fixed base 1.

[0060] In addition, one of the fixed base 1 and the rotatable cover 2 extends an annular gear 6 arranged parallel to the annular groove 31, and the other of the fixed base 1 and the rotatable cover 2 extends one or more convex teeth 7. The convex teeth 7 are engaged with the annular gear 6, so that when the user rotates the rotatable cover 2 with a finger, a scale feeling is generated when the convex teeth 7 slide across the annular gear 6.

[0061] Furthermore, each elastic arm 32 of this embodiment has an upright arm 321 extending along the axial direction of the annular groove 31 and a clamping block 322 protruding from the end of the upright arm 321. Each clamping block 322 is slidably engaged with the annular groove 31 along the circumferential and axial directions of the annular groove 31, but it is not limited thereto.

[0062] Among them, the annular gear 6 of this embodiment is arranged above the annular groove 31, and each convex tooth 7 extends from the top of a part of each clamping block 322. The annular groove 31 and the annular gear 6 are formed on the inner peripheral edge of the rotatable cover 2. A guiding slope 21 is provided on the inner peripheral edge of the rotatable cover 2, which is arranged below the annular groove 31 and gradually reduces in thickness in a direction away from the annular groove 31. A plurality of upright arms 321 extend from the top of the circular tube wall 12 and are arranged side by side at intervals. Each clamping block 322 is an angled block 323 that gradually reduces in thickness in a direction away from the circular tube wall 12 and can abut against the guiding slope 21, but it is not limited thereto. The annular groove 31 and the annular gear 6 can also be formed on the outer peripheral edge of the circular tube wall 12, and the elastic arms 32 and the convex teeth 7 can also be formed by extending from the rotatable cover 2.

[0063] As Figure 1 、 Figure 3 、 Figure 5 shown, the elastic component 4 is elastically supported between the fixed base 1 and the rotatable cover 2 to push the rotatable cover 2 to rise relative to the fixed base 1. The elastic component 4 is an elastic rubber cap 41 elastically supported between the shaft rod 111 and the inner bottom wall of the accommodating hole 241. The elastic rubber cap 41 extends a convex block 411 fitted into the positioning hole 112, so that the elastic rubber cap 41 is firmly engaged on the shaft rod 111.

[0064] As Figure 1 、 Figures 3 to 6As shown, the touch component 5 includes a first touch pad 51, a second touch pad 52, a first connecting piece 54 and a second connecting piece 55 made of a conductive material. The first connecting piece 54 is connected between the first setting part 22 and the first touch pad 51 and pushes the first touch pad 51 against the bottom plate 11 so that the bottom plate 11 and the first touch pad 51 are in an electrically conductive state. The second connecting piece 55 is connected between the second setting part 23 and the second touch pad 52 and pulls to form a distance S between the second touch pad 52 and the bottom plate 11 so that the bottom plate 11 and the second touch pad 52 are in a resistive disconnection state. When the rotatable cover 2 is pressed and descends relative to the fixed base 1, it will drive the second touch pad 52 to abut against the bottom plate 11 so that the bottom plate 11 and the second touch pad 52 are in an electrically conductive state.

[0065] Further description is as follows. A central axis 53 protrudes from each of the first touch pad 51 and the second touch pad 52. The first connecting piece 54 and the second connecting piece 55 are respectively a helical spring 56 with one end inserted into each concave hole 251 and the other end sleeved on each central axis 53. And the tapered hole section 253 is used to guide one end of the helical spring 56 to be tightly inserted into the blind hole section 252. Each central axis 53 extends with a tenon 531 for engaging the other end of each helical spring 56.

[0066] As Figures 3 to 4 shown, in one use state of the push-button rotatable switch 10 of the present utility model, it utilizes the first connecting piece 54 to be connected between the first setting part 22 and the first touch pad 51 and push the first touch pad 51 against the bottom plate 11 so that the bottom plate 11 and the first touch pad 51 are in an electrically conductive state. When the user rotates the rotatable cover 2, it will drive the first touch pad 51 to rotate accordingly, and then the first touch pad 51 performs a rotational touch on the virtual knob displayed on the bottom plate 11 (touch panel) so as to achieve the function of rotational touch of the push-button rotatable switch 10.

[0067] In addition, at this time, the rotatable cover 2 is not pressed by the user, so the second connecting piece 55 is connected between the second setting part 23 and the second touch pad 52 and pulls to form a distance S between the second touch pad 52 and the bottom plate 11 so that the bottom plate 11 and the second touch pad 52 are in a resistive disconnection state.

[0068] As Figures 5 to 6 shown, in another use state of the push-button rotatable switch 10 of the present utility model, when the rotatable cover 2 is pressed by the user and descends relative to the fixed base 1, it will drive the second touch pad 52 to abut against the bottom plate 11 so that the bottom plate 11 and the second touch pad 52 are in an electrically conductive state, and then the second touch pad 52 performs a press touch on the virtual knob displayed on the bottom plate 11 (touch panel) so as to achieve the function of press touch of the push-button rotatable switch 10.

[0069] Furthermore, the push-button type rotary switch 10 of the present utility model utilizes the elastic arms 32 to be circumferentially and axially slidably engaged with the annular groove 31 along the annular groove 31, so as to achieve the actions of the rotatable cover 2 being rotatable and liftable relative to the fixed base 1 with a simple structure. Moreover, the elastic arms 32 can be stably engaged with the annular groove 31, making the push-button type rotary switch 10 have the advantages of simple assembly structure, stability and cost saving.

[0070] As Figure 7 shown, it is another embodiment of the push-button type rotary switch 10 of the present utility model. Figure 7 The embodiment of Figures 1 to 6 is substantially the same as the embodiment of Figure 7 The difference between the embodiment of Figures 1 to 6 and the embodiment of

[0071] is that the structure of the elastic arm 32 is different. The details are as follows. Each elastic arm 32 of this embodiment has a vertical arm 324 extending along the circumference of the annular groove 31 and a clamping block 322' protruding from the end of the vertical arm 324. Each clamping block 322' can be circumferentially and axially slidably engaged with the annular groove 31, but not limited thereto, so that the rotatable cover 2 can be rotatably and liftably connected above the fixed base 1. Thereby, the same functions and effects as the embodiment of Figures 1 to 6 are achieved.

[0072] In addition, the annular groove 31 of this embodiment is formed on the outer periphery of the circular pipe wall 12, and a plurality of vertical arms 324 extend from the inner periphery of the rotatable cover 2, but not limited thereto. A plurality of vertical arms 324 can also extend from the outer periphery of the circular pipe wall 12, and the annular groove 31 can also be formed on the inner periphery of the rotatable cover 2.
