The touch key cap is a key of the keyboard, and the key cap includes a touch IC1, a PCB 2, and an elastic connector 3. The touch IC1 is located above and closer to the location where the user presses. Specifically, the touch IC1 can generate a corresponding touch signal in response to a touch operation by a user, typically a touch operation.
The PCB 2 is located below the touch IC1, the elastic connector 3 is disposed between the PCB 2 and the touch IC1, and the mechanical pressing trigger 4 is disposed on a side of the PCB 2 facing the touch IC 1. The mechanical pressing trigger 4 can be specifically a dome sheet (dome sheet), a metal patch key, a touch capacitor and other structures which need to be pressed by an entity to generate a corresponding signal, so that when a touch key cap is pressed, the stroke of the elastic connecting piece 3 can be compressed to trigger the mechanical pressing trigger 4, namely, the elastic connecting piece 3 is compressed to trigger the mechanical pressing trigger 4 to generate a pressing signal, and the traditional mechanical pressing structure is realized. In general, the pressing signal may be directly transmitted to the PCB. The elastic connecting member 3 may be a spring or any other elastic member, and as the case may be, the specific structures of the elastic connecting member 3 and the mechanical pressing trigger 4 may refer to the prior art, which is not described herein again.
The mechanical pressing trigger 4 is arranged on the surface of the PCB 2 facing the touch IC1, so that the mechanical pressing trigger 4 can be responded by the PCB 2 in time when triggered; the touch IC1 needs to be in communication with the PCB 2, so that when the touch function of the touch IC1 is triggered or responded, the touch signal can be timely transmitted to the PCB 2.
