[0023] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0024] Example 1:

[0025] like Figure 1 - Figure 3 As shown, the utility model provides a dual-light color tact switch, including a base 1, a button 2 that can slide vertically along the base 1 is provided at the internal upper end of the base 1, a reed 3 is installed at the internal bottom end of the base 1, and two groups of switch pins 4 are installed at the bottom end of the base 1. The two groups of switch pins 4 are respectively electrically connected to the positive and negative poles of the reed 3. A dual-color LED lamp group 6 is provided inside the button 2. The dual-color LED lamp group 6 includes a dual-color LED lamp 61 and several groups of dual-color LED lamp pins 62. The dual-color LED lamp 61 is provided inside the button 2, and several groups of dual-color LED lamp pins 62 are respectively electrically connected to the positive and negative poles of the dual-color LED lamp 61. The dual-color LED lamp pins 62 are in contact with the side wall of the base 1.

[0026] The bi-color LED lamp 61 is supported by the bi-color LED lamp pins 62. The bi-color LED lamp 61 maintains its own fixed position under the support of the bi-color LED lamp pins 62. One group of bi-color LED lamp pins 62 is electrically connected to the reed 3 and the switch pin 4. The bi-color LED lamp 61 increases the luminous color according to the connection status of the switch pin 4 and the reed 3. Another group of bi-color LED lamp pins 62 is electrically connected to the external PCB board for power supply, so that one group of color lights in the bi-color LED lamp 61 remains always on.

[0027] The base 1 includes a base body 11 and a pin limiting portion 12;

[0028] A pressing chamber is formed inside the base body 11, and the button 2 is arranged in the pressing chamber. The pin limiting part 12 is formed at the bottom end of the outer wall of the base body 11. A through hole is opened in the middle of the pin limiting part 12 for the two-color LED lamp pin 62 to pass through. The two-color LED lamp pin 62 passes through the through hole, and the pin limiting part 12 limits the two-color LED lamp pin 62 by the friction between the inner wall of the through hole and the two-color LED lamp pin 62. Under the restriction of the pin limiting part 12, the two-color LED lamp pin 62 can support the two-color LED lamp 61 to remain at the initial setting position, and the setting position of the two-color LED lamp 61 will not move synchronously with the pressing of the button 2.

[0029] The bottom of the button 2 extends outward to form a protruding outer edge. The outer surface of the outer edge of the button 2 conflicts with the inner wall of the pressing chamber. The button 2 is supported and restricted by the pressing chamber of the base body 11. With the support of the base body 11, the vertical movement of the button 2 can remain stable without lateral deviation, thereby ensuring the stability of the pressing and avoiding the button 2 from affecting the setting state of the two-color LED light 61.

[0030] The base cover 5 is installed at the end of the base 1, and the middle part of the button 2 is formed with an annular groove that cooperates with the base cover 5. The button 2 is clamped in the base cover 5 through the annular groove. The base cover 5 restricts the button 2 by cooperating with the annular groove. The base cover 5 further restricts the vertical movement of the button 2 and limits the movable distance of the button 2, so that the button 2 will not fall out from the inside of the base body 11.

[0031] A cavity is opened inside the button 2 for the dual-color LED light group 6 to be set. The dual-color LED light group 6 is set in the cavity. The vertical height of the cavity is higher than the stroke height of the button 2 in the pressing cavity. Within the stroke range of the button 2, the movement of the button 2 will not push the dual-color LED light group 6, thereby ensuring that the dual-color LED light group 6 is always in the initial setting position to ensure the normal operation of the dual-color LED light group 6.

[0032] Example 2:

[0033] like Figure 4As shown, the utility model provides a dual-light color touch switch, including a base 1, a button 2 that can slide vertically along the base 1 is provided at the internal upper end of the base 1, a reed 3 is installed at the internal bottom end of the base 1, and two groups of switch pins 4 are installed at the bottom end of the base 1. The two groups of switch pins 4 are respectively electrically connected to the positive and negative poles of the reed 3. A plurality of groups of single-color LED light groups 7 are provided in the internal cavity of the button 2. The single-color LED light group 7 includes a single-color LED lamp 71 and a plurality of groups of single-color LED lamp pins 72. The single-color LED lamp 71 is provided in the internal cavity of the button 2, and the plurality of groups of single-color LED lamp pins 72 are respectively connected to the positive and negative poles of the single-color LED lamp 71. The monochromatic LED lamp pin 72 passes through the through hole, and the pin limiting portion 12 limits the monochromatic LED lamp pin 72 through the friction between the inner wall of the through hole and the monochromatic LED lamp pin 72. The specifications of several groups of monochromatic LED lamps 71 are different, and the colors emitted by each group of monochromatic LED lamps 71 are different. One group of monochromatic LED lamps 71 is electrically connected to the reed 3 and the switch pin 4 through the monochromatic LED lamp pin 72, and the other group of monochromatic LED lamps 71 is electrically connected to the PCB board, receives power from the PCB board and remains always on. When the reed 3 and the switch pin 4 are turned on, one group of monochromatic LED lamps 71 is powered on and emits light, which is used to judge the on state.

[0034] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
