When the light-emitting knob is in a switch-off position, the first contact portion 411 of the conductive elastic sheet 410 is located at the position of the inner ring disconnection portion 511, but is not in conductive connection with the conductive inner ring 510, so that the conductive inner ring 510 and the conductive outer ring 520 are not in conductive connection, and the LED light source 530 does not emit light, so that the light-emitting knob does not emit light when being in the switch-off position, that is, the light-emitting knob does not emit light during non-use, and electric energy is saved. Here, the inner ring breaking portion 511 may be an insulating portion on the surface of the LED lamp panel 500, or may be a hollow structure on the LED lamp panel 500.

Referring to fig. 5, a second structure that makes the light emitting knob not emit light when it is in the off position: an outer ring break 521 is provided to the conductive outer ring 520. When the light-emitting knob is in the off position, the second contact portion 412 of the conductive elastic sheet 410 is located at the position of the outer ring disconnection portion 521, rather than being conductively connected with the conductive outer ring 520, so that the conductive inner ring 510 and the conductive outer ring 520 are not conducted, and further the LED light source 530 does not emit light, so that the light-emitting knob does not emit light when being in the off position, that is, the light-emitting knob does not emit light during non-use, and electric energy is saved. Here, the outer ring breaking portion 521 may be an insulating portion on the surface of the LED lamp panel 500, or may be a hollow structure on the LED lamp panel 500.

Here, the inner ring breaking portion 511 and the outer ring breaking portion 521 may be insulating portions on the surface of the LED lamp panel 500, or may be hollow structures on the LED lamp panel 500.

During the rotation of the light-emitting knob, the second contact portion 412 of the conductive elastic piece 410 is always conducted with the conductive outer ring 520, but the first contact portion 411 of the conductive elastic piece 410 is conducted with different inner ring conductive arcs 512 along with the rotation, and the different inner ring conductive arcs 512 correspond to different LED light sources 530, so that the light-emitting knob controls the different LED light sources 530 to emit light during the rotation. Here, it should be noted that, in order to match the position of the LED light source 530 emitting light with the position of the gear position to which the light emitting knob is rotated, the LED light source 530 may be arranged along the edge of the knob base 200 in an arc shape.

Referring to fig. 9, 12 and 15, a second configuration for controlling the different LED light sources 530 to emit light during rotation of the light emitting knob: the conductive outer ring 520 is designed to have at least two segments of outer ring conductive arcs 522, and the number of the LED light sources 530 matches the number of the outer ring conductive arcs 522. During the rotation of the light-emitting knob, the first contact portion 411 of the conductive dome 410 is always conducted with the conductive inner ring 510, but the second contact portion 412 of the conductive dome 410 is conducted with different outer ring conductive arcs 522 along with the rotation, and the different outer ring conductive arcs 522 correspond to different LED light sources 530, so that the light-emitting knob controls the different LED light sources 530 to emit light during the rotation. Here, it should be noted that, in order to match the position of the LED light source 530 emitting light with the position of the gear position to which the light emitting knob is rotated, the LED light source 530 may be arranged along the edge of the knob base 200 in an arc shape.

Referring to fig. 10, 13 and 16, a third configuration for controlling the different LED light sources 530 to emit light during rotation of the light emitting knob: the conductive inner ring 510 is designed to be at least two segments of inner ring conductive arcs 512, and the conductive outer ring 520 is designed to be at least two segments of outer ring conductive arcs 522, wherein the inner ring conductive arcs 512 and the outer ring conductive arcs 522 correspond one to one.

Here, it should be noted that, in order to match the position of the LED light source 530 emitting light with the position of the gear position to which the light emitting knob is rotated, the LED light source 530 may be arranged along the edge of the knob base 200 in an arc shape.
