Description

Technical Field

[0001] This utility model relates to a switch, and more particularly to a tactile coded combination switch. Background Technology

[0002] A tactile encoder combination switch is a type of control switch that integrates a tactile switch within an encoder, achieving both rotary encoding and button functions through pin design. A traditional tactile encoder combination switch structure, as shown in Chinese Utility Model Patent No. "CN210089714 U" entitled "An Encoder with LED Light," uses a central shaft to control both the rotation of the turntable and the pressing of the metal spring (commonly known as a dome switch). The disadvantages are that in practical applications, this can easily lead to operational confusion, and rotating and pressing the relatively thin central shaft is quite difficult. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tactile coded combination switch that is more convenient to operate by rotation and pressing and is less prone to confusion.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: an encoder and a tactile switch disposed at the center of the encoder. The encoder includes a base, a code disk disposed in the base, a turntable rotatably disposed on the base, and a brush disposed at the bottom of the turntable in contact with the code disk. The tactile switch includes a base, a set of terminals disposed in the base, a metal spring disposed in the base for connecting the terminals, and a pressing rod disposed at the upper end of the base for pressing the metal spring. The base is mounted on the upper end of the base, a knob is connected to the upper end of the turntable, and a button is connected to the upper end of the pressing rod, with the pressing surface of the button located at the center of the knob.

[0005] The pressing rod is mounted on the upper end of the base via a first metal fixing frame. The first metal fixing frame is provided with a first fixing foot for fixing the base and a second fixing foot for fixing the base.

[0006] The lower end of the knob is riveted to a mounting bracket, the mounting bracket is provided with a set of buckles, and the turntable is provided with a first slot that connects to the buckles.

[0007] The turntable is mounted on the base via a second fixing bracket, which has a third fixing foot fixed to the base and a fourth fixing foot for assembly.

[0008] The lower end of the turntable is provided with a wave-shaped gear groove, and the base is provided with a gear plate, one end of which is provided with a protrusion that abuts against the gear groove.

[0009] The gear shift plate is circular and has locking plates at both ends. The base has a second slot that engages with the locking plates.

[0010] The upper end of the pressing rod is provided with straight teeth, which are riveted to the button.

[0011] The base contains an LED circuit board, and the LED circuit board has LED beads located below the pressing rod. Both the pressing rod and the button are light-transmitting.

[0012] The advantages of this tactile encoder combination switch are: by combining the encoder and tactile switch in a more reasonable way, rotation is completed by a knob and pressing is completed by a button, making rotation and pressing operations more convenient and less likely to be confused.

Detailed Implementation

[0015] like Figure 1-6 As shown, the tactile encoder combination switch of this utility model includes an encoder 1 and a tactile switch 2 disposed at the center of the encoder 1. The encoder 1 includes a base 3, a code disk 4 disposed in the base 3 by injection molding, a turntable 5 rotatably disposed on the base 3, and a brush 6 disposed at the bottom of the turntable 5 in contact with the code disk 4. The tactile switch 2 includes a base 7, a set of terminals 8 disposed in the base 7, a metal spring 9 disposed in the base 7 for connecting the terminals 8, and a pressing rod 10 disposed on the upper end of the base 7 for pressing the metal spring 9. The base 7 is mounted on the upper end of the base 3. A knob 11 is connected to the upper end of the turntable 5, and a button 12 is connected to the upper end of the pressing rod 10, with the pressing surface 13 of the button 12 located at the center of the knob 11.

[0016] Preferably, the pressing rod 10 is mounted on the upper end of the base 7 via a first metal fixing frame 14. The first metal fixing frame 14 is provided with a first fixing foot 15 for fixing the base 7 and a second fixing foot 16 for fixing the base 3. The pressing rod 10 is rotatably disposed within the first metal fixing frame 14 and is positioned by a flange 31 at its lower end. This achieves a stable connection between the base 7 and the base 3.

[0017] Preferably, a mounting bracket 17 is riveted to the lower end of the knob 11, and a set of buckles 18 are provided on the mounting bracket 17. The turntable 5 is provided with a first slot 19 that connects to the buckles 18. Through the above structure, the knob 11 and the turntable 5 can be detachably assembled, thereby facilitating the overall assembly of the product.

[0018] Preferably, the turntable 5 is mounted on the base 3 via a second fixing bracket 20. The second fixing bracket 20 is provided with a third fixing foot 21 fixed to the base 3 and a fourth fixing foot 22 for assembly. The fourth fixing foot 22 is used for connection with the application object (such as a PCB board). The turntable 5 is also positioned with the second fixing bracket 20 via a flange at its bottom.

[0019] Preferably, the lower end of the turntable 5 is provided with a wave-shaped gear groove 23, and the base 3 is provided with a gear plate 24, one end of which is provided with a protrusion 25 that abuts against the gear groove 23. Because the gear plate 24 has good elasticity, it can position the turntable 5 during rotation to produce gears.

[0020] Preferably, the shift plate 24 is annular and has retaining plates 26 at both ends. The base 3 has a second retaining groove 27 that engages with the retaining plates 26. After the retaining plates 26 of the shift plate 24 are engaged in the second retaining groove 27, it is then fixed by the second fixing bracket 20. This facilitates the installation of the shift plate 24.

[0021] Preferably, the upper end of the pressing rod 10 is provided with straight teeth 28, which are riveted to the button 12. The bottom of the button 12 is provided with a riveting hole with an inner diameter slightly smaller than the outer diameter of the pressing rod 10, so as to achieve a stable connection between the pressing rod 10 and the button 12.

[0022] Preferably, the base 7 contains an LED circuit board 29, and the LED circuit board 29 has LED beads 30 located below the pressing rod 10. Both the pressing rod 10 and the button 12 are light-transmitting, thus realizing the on / off function of the switch.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
