Abstract

The application discloses a key and electronic equipment, and relates to the technical field of keys, wherein the key comprises a pressing part and a voltage stabilizing structure arranged on the pressing part, the top of the pressing part is provided with a pressing position, the bottom of the pressing part is provided with a deformation cavity, and the deformation cavity is communicated with the external space of the pressing part through the voltage stabilizing structure. According to the technical scheme, the pressure stabilizing structure is arranged, so that the deformation cavity can be communicated with the outer space of the pressing part through the pressure stabilizing structure, after the pressure applied to the pressing position is canceled, the air pressure in the deformation cavity can be balanced with the outer space of the pressing part, and the deformation cavity can be quickly restored to deform, so that the condition that the pressure in the deformation cavity is lower than the external air pressure when the pressing part rebounds, and the pressing part cannot rebound normally is prevented, and therefore the rebound effect of the key is improved.
