    摘要： An object of the invention is to provide a vacuum switch (70) which can achieve a reduction of an electric loss and an improvement of a heat transmission performance by preventing an air gap portion from being generated between an electrode and a conductor rod (1) and preventing the electrode and the conductor rod (1) from generating any positional displacement. An electrode for a switch in accordance with the invention is provided with the conductor rod (1), a contact point electrode (2) inserted to the conductor rod (1), and a coupling plate (3) fixing both the elements to an outer side in a diametrical direction of the conductor rod (1) and the contact point electrode (2), thereby fixing both the elements.
