Abstract
A switching system using laser induced discharge is provided which is capable of reliable switching with a simple structure, multiple switching for a number of circuits, good synchronization and no switching time delay among circuits. In the switching system for controlling conduction between electrodes of a switch by discharge between the electrodes, a laser beam is applied to one of the electrodes to make discharge from the other of the electrodes be induced by the laser beam and application of the laser beam is controlled to switch the conduction.
