Abstract
PURPOSE:To prevent the generation of chattering in make and break time of a changeover switch of an on-load tap changer by a method wherein a movable contact is supported rotatably on either-side in a metallic holder having shaped sectional area, a pressing spring is put between the inside face adjoining to the bridging part of metallic holder and a side place of abovementioned contact opposite to making direction and the abovementioned contact is made to be inclined in the metallic holder to the making direction. CONSTITUTION:A metallic holder 8 having a sectional area of shape is equipped at tip of a sliding shaft 7 which penetrates a supporting wall 6 forming a concentric circle with a fan-shaped movable plate C1 to the radiating directon, and a movable contact B1 is fitted up with a pin 9 in the metallic holder 8 rotatably on either side. A spring holding hole 15 is prepared on the inside face of the contact B1 adjoining to the bridge part 8' of the metallic holder 8 put aside a little from the center line X of the sliding shaft 7, and a pressing spring 14 is put in the spring holding hole 15 to press the contact B1 from one side to make it to be inclined in making direction. As a result, when the fan-shaped movable plate is rotated, chattering caused by the change of position or sliding on a fixed contact of the movable contact does does not occur.
