detailed description

The principles and spirit of the present invention are described below with reference to the exemplary embodiments. It is to be understood that the description of the embodiments is merely intended to enable a person skilled in the art to understand the invention.

1 is an exploded view of a switch in accordance with an exemplary embodiment of the present invention and FIGS. 2a, 2b are perspective and partial enlarged views of a switch in accordance with an exemplary embodiment of the present invention. As shown in FIGS. 1, 2a and 2b, a switch 10 according to an embodiment of the present invention includes: a switch panel 2, and a translucent cover 1, a xenon tube 3, and a fixing piece 4 mounted on the switch panel 2, wherein The trachea 3 is located between the translucent cover 1 and the fixed piece 4. In addition, the switch 10 also includes a switch rocker and a switch function body.

2b, the switch panel 2 is provided with a hole 25 (see FIG. 4c) for accommodating the xenon tube 3, the shape of which is adapted to the shape of the xenon tube 3, for example cylindrical; the transparent cover 1 is mounted on the switch panel 2 is located above the hole 25 for emitting light of the xenon tube 3 therethrough. In the embodiment shown in Figure 2b, the top of the transparent cover 1 is flush with the upper surface of the switch panel 2, and in other embodiments, the top portion may be convex or recessed relative to the upper surface of the switch panel 2, the transparent cover 1 Located above the xenon tube 3, a fixing piece 4 is provided below the switch panel 2 (and the xenon tube 3), which is fixed to the switch panel 2 such that the xenon tube 3 is located between the transparent cover 1 and the fixed piece 4.

As shown in FIG. 3, the transparent cover 1 for the user to observe the illumination of the xenon tube 1 includes a step surface 11 and a bone surface 12, corresponding thereto, as shown in FIGS. 2a and 2b, the bone plate above the hole 25 of the switch panel 2 has a bone position. 21 and step surface 22. When the transparent cover 1 is mounted on the switch panel 2, the bone plane 12 on the transparent cover 2 and the bone position 21 on the switch panel 2 are interference fit, the step surface 11 on the transparent cover 1 and the step on the switch panel 2 The faces 22 are in contact with each other, thereby firmly fixing the transparent cover 1 to the switch panel 2.

As shown in Fig. 2b and Fig. 4b, the lower portion of the switch panel 2 is provided with pillars 23, the number of which is two, and the pillars 23 pass through the holes 41 of the fixing piece 4 below the switch panel 2 (see Fig. 6), and then The end of the column 23 is subjected to cold staking riveting molding, thereby fixing the fixing piece 4 It is fixed to the switch panel 2, thereby preventing the blowpipe 3 from falling from the hole 25.

As shown in FIG. 5, the xenon tube 3 includes a borosilicate glass tube 31, and may be other high temperature resistant glass tubes, a fluorescent coating 33 coated on the inner wall of the glass tube, and a helium gas 32 inside the glass tube. Its working principle is: helium will release a small amount of electron flow evenly, and stimulate the fluorescent material on the tube wall to make it emit light. In one embodiment, a small amount of phosphide may be charged in the xenon tube to change the color of the xenon tube. According to the phosphide content, the xenon tube has green, red, blue, yellow, purple, orange, and white colors. .

The number and arrangement of the xenon tubes can be varied as desired, for example, can be arranged around the circumference of the switch panel, and in one embodiment, the xenon tube can be placed on the switch pad to reflect the on/off state of the switch.
