In the 1879, the Dual alliance (Germany and Austria) was made and then Italy joined in 1882 which made the Triple alliance.
Italy was part of the triple Alliance up until the beginning of World War I; however since Italy was completley unprepared for war and did not want to risk war with Britain and France due to their much greater naval power and Italy's vulnerability to attack by sea. Therefore Italy abrogated the Triple Alliance treaty and remained neutral when Germany and Austria went to war in 1914.
No country switched from the Triple Alliance to the Triple Entente. The Triple Entente consisted of the Russian Empire, France's Third Republic, and the United Kingdom (England & Ireland), supplemented by agreements with Portugal and Japan while the Triple Alliance was made up of Germany, Austria-Hungary, and Italy. Italy however, joined the Allied side during WW1.
In world war one there were two sides: The Triple Entente contained The United Kingdom, Russia and France and The Triple Alliance contained Germany, Austria-Hungary and Italy. However, later on in the war, in April 1915 Italy changed sides to the Triple Entente.
