A kind of crank handle device of built-in motor short circuit brake control switch can store type crank handle portion and motor short circuit brake control switch comprising an interconnecting piece, one； It includes a drive-connecting shaft and a handle that this, which can store type crank handle portion,. When the handle draws close the drive-connecting shaft, motor short circuit brake control switch is touched and is connected, therefore a short circuit brake circuit makes a motor apparatus short circuit brake； When the handle does not draw close the drive-connecting shaft, therefore motor short circuit brake control switch is not touched to be not turned on, therefore short circuit brake circuit does not make the motor apparatus short circuit brake.一種內建馬達短路煞車控制開關之手搖曲柄裝置，包含一連接部、一可收納型手搖曲柄部及一馬達短路煞車控制開關；該可收納型手搖曲柄部包含一樞接軸及一握把。當該握把靠攏該樞接軸時，該馬達短路煞車控制開關被觸碰而導通，因此一短路煞車迴路使一馬達裝置短路煞車；當該握把不靠攏該樞接軸時，該馬達短路煞車控制開關不被觸碰因此不導通，因此該短路煞車迴路不使該馬達裝置短路煞車。
