摘要： An object of the invention is to provide a vacuum switch 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 and preventing the electrode and the conductor rod from generating any positional displacement. An electrode for a switch in accordance with the invention is provided with the conductor rod, a contact point electrode inserted to the conductor rod, and a coupling plate fixing both the elements to an outer side in a diametrical direction of the conductor rod and the contact point electrode, thereby fixing both the elements.
