Patent ID: 7920075

Claim:
A regulation control device, comprising: an encoder mechanism including a base, a printed circuit board(PCB), and an encoder, wherein the PCB has a touch switch arranged on a side of the PCB, a fixed shaft on a opposite side of the PCB is arranged in the base, and the encoder is connected with the base and electrically connected to the PCB; and a shell set including a press shell, a connecting seat, a rotating seat, and a supporter, wherein the press shell is arranged on a side of the base and corresponded to the touch switch for press, the connecting seat is arranged on the other side of the base, connected to the encoder, and arranged in the rotating seat connected to the connecting seat so that the connecting seat and the rotating seat can be assembled with the encoder in a rotation way, the supporter is arranged on a side between the connecting seat and the rotating seat, and one end of the fixed shaft is connected to the supporter; wherein the encoder includes: a body that is set and connected to the base out of the fixed shaft and includes a plurality of metal pins respectively stretching from the inside of the body to the outside of the body and being electrically connected to the PCB; a rotation part that rotatably connect to the body and protrude to form with a plurality of conductive parts that are electrically conductive with the metal pins in a rotation way, in which the connecting seat is wedged into the rotation part; and a mounting part that fixes the body and the rotation part and connects to the base.
