Touch keycap, keyboard, and keyboard touch input assembly

A touch keycap, comprising a circuit board and a keycap body, wherein the circuit board is located on the keycap body and/or a keyboard;

• the circuit board is provided with a touch circuit;
• the touch circuit is electrically connected to a capacitive sensing touch element;
• the capacitive sensing touch element is one or more of a touch key, a touch slider, and a touch pad;
• the touch circuit is provided with a microcontroller unit (MCU);
• the capacitive sensing touch element is electrically connected to the MCU;
• the capacitive sensing touch element is located at any position of an inner surface, an interior, and an outer surface of a top wall of the keycap body;
• alternatively, the capacitive sensing touch element is located at any position of an inner surface, an interior, and an outer surface of a side wall of the keycap body;
• and alternatively, the capacitive sensing touch element is located at an edge of the keycap body.
