[0033] In this embodiment, a control circuit is arranged in the support shell 100, and the switch circuit board 310 is electrically connected to the control circuit, and the control circuit is also connected to a light source body and a lighting lamp 500 on the emergency indicating lamp 10. The circuit on the switch circuit board 310 is electrically connected to the switch body 320, so that when the switch light guide 340 is pressed on the switch body 320, the switch body 320 generates a signal, the control circuit receives the signal, and controls the light source body and / or the lighting lamp 500 to work or close. In addition, the circuit on the switch circuit board 310 is also electrically connected to the switch indicating lamp 330 and supplies power to the switch indicating lamp 330, for example, the switch indicating lamp 330 is a LED (light-emitting diode) lamp bead, and after the switch indicating lamp 330 is powered on, the light is transmitted to the switch light guide 340, the switch light guide 340 guides the light to the outside through the mounting hole 103, thereby forming the light-emitting effect of the switch light guide 340, so that the user can see the switch light guide 340 in the dark environment, and therefore, the switch light guide 340 not only has the function of switch, but also can emit light.

[0034] In the above embodiment, by arranging the switch light guide member 340 at the bottom of the support shell 100, when the switch indicator lamp 330 emits light, the light is guided to the outside by the switch light guide member 340, so that the switch light guide member 340 emits light, and further, the switch light guide member 340 can not only realize the control of the opening and closing of the emergency indicator lamp 10, but also emit light when used in a relatively dark environment, so that the indication switch assembly 300 is more easily identified.

[0035] In one embodiment, as shown in Figure 4 The switch light guide member 340 includes a pressing portion 341 and a light guide portion 342, the pressing portion 341 extends along a first direction, and the light guide portion 342 extends along a second direction, wherein the second direction is from the switch circuit board 310 to the mounting hole 103, the first direction is perpendicular to the second direction, the width of the pressing portion 341 in the first direction is greater than the width of the light guide portion 342 in the first direction, the pressing portion 341 movably abuts against the switch body 320, and the pressing portion 341 covers the switch indicator lamp 330.

[0036] In one embodiment, referring again to Figure 4 , the extension directions of the pressing portion 341 and the light guide portion 342 are perpendicular to each other, that is, the pressing portion 341 and the light guide portion 342 are connected in an L shape.

[0037] In this embodiment, the pressing portion 341 is arranged in the mounting cavity 102, and the end of the light guide portion 342 away from the pressing portion 341 passes through the mounting hole 103 and is at least partially exposed outside the mounting cavity 102. Since the light guide portion 342 protrudes to the outside of the mounting cavity 102, it can present a light emitting effect outside and is easy for the user to press. In this embodiment, the width of the pressing portion 341 in the first direction is larger, which is beneficial to fully cover the switch body 320 and the switch indicator lamp 330, can fully press the switch body 320, and can better and fully guide the light of the switch indicator lamp 330 to the outside.

[0038] In order to make the movement of the switch light guide member 340 more stable, in one embodiment, a guide structure is arranged in the mounting cavity 102, and the switch light guide member 340 moves along the guide structure in the second direction, wherein the second direction is from the switch circuit board 310 to the mounting hole 103.
