Key device and control structure thereof

The invention discloses a key device and a control structure thereof. The control structure comprises a plurality of reset brackets and a plurality of transparent key bodies which are respectively fixed on the plurality of reset brackets. Each reset bracket comprises an elastic section, a fixing section and a setting section, wherein the fixing section and the setting section are connected to the two opposite ends of the elastic section. Each transparent key body comprises a pressing part and an abutting part. In each transparent key body, the pressing part is fixed on the fixed section of the corresponding reset bracket and is provided with a contact surface far away from the corresponding reset bracket, the abutting part is formed by extending from the pressing part to a displacement direction far away from the contact surface, and the width of the abutting part is smaller than that of the pressing part. And the contact surface of any transparent key body can be pressed to move along the displacement direct
