Key with floating touch function

The utility model discloses a key with a suspension touch control function. The key comprises a base, an elastic piece, a pressing piece, a display screen, a capacitance touch control layer and an outer protection layer, the pressing piece is arranged in the base, the elastic piece is arranged below the pressing piece, wiring electrodes are arranged on the two sides of the base, and the pressing piece can be electrically connected with the two wiring electrodes. A display screen, a capacitive touch layer and an outer protection layer are sequentially arranged on the outer surface of the pressing piece and are fixed into a whole; the capacitance touch control layer is a self-capacitance inductive sensor or a mutual-capacitance inductive sensor, and the outer protection layer is a glass cover plate. According to the utility model, a suspension/non-contact capacitance touch control function is added on the basis of mechanical triggering, so that a corresponding key/button instruction can be activated without tou
