Abstract
A thyristor comprising a thyristor element with a trigger section 1a formed on the surface thereof. The thyristor element is attached to a metal disk 2 having at least three faces 2a on its periphery which are all a common distance l from the center of the trigger section. One electrode unit 4 is attached to the opposing surface of the metal disk and a second electrode unit 3 is attached to the opposing surface of the thyristor element. A trigger signal guide 10 penetrates an insulating tube 5 surrounding the element and one end of the guide is positioned on the central axis of the insulating tube. Positioning members 11 of equal width are compressively inserted between the insulating tube and the faces of the metal disk.
