Abstract
There is provided a light triggered thyristor device comprising a main thyristor triggered by an electric triggering signal, an auxiliary thyristor triggered by a light signal applied to a light receiving portion, the auxiliary thyristor then supplying the electric triggering signal from a cathode thereof to a gate of the main thyristor, a cylindrical insulator for containing the main thyristor, a connector mechanism disposed near an end of an anode on a side face of the main thyristor and electrically connected to the anode of the main thyristor, the connector mechanism having one end side exposed to outside of the cylindrical insulator, the auxiliary thyristor being so attached to one end side of the connector mechanism as to enable their free connection and disconnection, the anode of the main thyristor being electrically connected to the anode of the auxiliary thyristor via the connector mechanism.
