A reversing switch for a tap changer of a transformer is provided. The reversing switch includes first and second contact structures for connection to a winding of the transformer and a mounting structure for connection to a neutral terminal of the transformer. A bus bar connects a third contact structure to the mounting structure. A movable contact arm is secured to a rotatable post. The contact arm includes a contact assembly mounted to an arm. The contact assembly has one or more outward contacts and one or more inward contacts. The one or more inward contacts engage the third contact structure and the one or more outward contacts selectively engage the first contact structure or the second contact structure. The first and second contact structures and the mounting structure are located at about the same radial distance from the post, while the third contact structure is located closer to the post.
