Abstract
A power switching apparatus in accordance with present disclosure includes a sun gear which can be driven to rotate in a first and second direction, an arm which can swing freely relative to the rotating axis of the sun gear. A transfer gear is pivotally provided at the arm for engaging with the sun gear. There is a pair of driven gears disposed a prescribed distance apart from each other in the circumferential direction of the sun gear so that each of said driven gears can engage independently with the transfer gear. A control device controls the position of the transfer gear so that the transfer gear can engage with one of the driven gears before initiation of rotation of the sun gear.
