[0002] Some function keys of special function on the keyboard often set some indicating lamps, and the traditional key indicating lamp is generally installed on the keyboard substrate and is lighted by the circuit at the bottom of the keyboard. This indicating lamp installation mode needs to arrange the indicating lamp on the key seat below the keycap. Since the scissors feet also need to be installed on the key seat, the space of the key seat is limited, so the scissors feet need to avoid the light-emitting position of the indicating lamp when being arranged, which causes that part of the scissors feet structure cannot be shared, and since the indicating lamp is at the bottom and the bottom of the key seat generally has a gap, the key side is prone to light leakage when the indicating lamp works, which affects the overall visual effect of the keyboard. In addition, under the backlight on state, the indicating lamp is prone to receiving the light source of the backlight, which causes the light surface to be slightly bright and the indicating light to be confused.

The scissors feet are installed at the bottom of the key seat provided on the keyboard substrate. The keycap pad is installed at the middle position of the key seat. The keycap is installed on the scissors feet. The receiving coil winding is fixed on the keycap. One corner of the top of the keycap is provided with a lamp hole. The function key indicating lamp is fixed on the inner side of the top of the keycap and is located directly below the lamp hole. The two poles of the receiving coil winding are connected with the function key indicating lamp. The transmitting coil winding is arranged on the keyboard substrate. The projection of the receiving coil winding on the keyboard substrate is located in the transmitting coil winding.

[0005] In one preferable embodiment of the utility model, the receiving coil winding is an ultra-thin FPC etching circuit, which is fixed on the inner side of the top of the keycap.

[0006] In one preferable embodiment of the utility model, the receiving coil winding is a varnished wire winding, which is fixed on the inner side of the top of the keycap.

[0007] In a preferred embodiment of the present application, the receiving coil winding is arranged around the contact area between the keycap rebound pad and the inner side of the top of the keycap, and is located within the outline formed by the connecting line of the contact point between the scissors leg and the top of the keycap.

[0008] In a preferred embodiment of the present application, the function key indicator light is an LED indicator light.

[0009] The present application has the following beneficial effects: by changing the power supply mode of the function key indicator light, the key indicator light can be separated from the keyboard substrate and installed on the inner side of the top of the keycap, thereby effectively solving the contradiction between the key indicator light and the scissors leg plane occupation, and through this way, on the one hand, the interference of the bottom backlight is isolated, on the other hand, the keycap bottom side light leakage phenomenon during lighting can be avoided, and the visual effect of the whole keyboard is improved.
