Abstract
The present invention relates to a load transfer switch for a tap changer, comprising permanent main contacts that switch powerlessly for each phase. The general inventive concept lies in connecting the fixed permanent main contacts of side A or B of the load transfer switch by means of a movable rail-shaped permanent main contact that establishes an electrical connection to the corresponding permanent main contacts of the load line only in the end positions of the movable rail-shaped permanent main contact and in addition only provides for a single deflection for actuation, which connects in a purely compressive manner the plurality of contact fins of the corresponding fixed permanent main contact, which contact fins are connected in a resilient, articulated manner.
