ABSTRACT:
A switching apparatus has a frame with a circular notch in its operating surface; a operating handle disposed in the notch, said handle can change from a lower position corresponding to automatic mode to a upper position corresponding to manual mode, and the handle are rotatable in said circular notch in both positions; and gearing mechanism disposed in the frame, said gearing mechanism comprise a main gear, a clutch gear coupled to a motor, and a switch gear coupled to the main gear. The main gear, the clutch gear and the handle consist of a clutch device, such that in automatic mode the main gear engages the clutch gear and in manual mode the main gear disengaged from the clutch gear. Because the motor is disengaged from the main gear in the manual mode, the rotation of the operating handle will not interact with motor, so avoids possible confliction and resultant damage.
