ABSTRACT:
The invention concerns a high coulomb transfer switch useful for high current pulse supplies, employing a self-bouncing arc mechanism, wherein two cylindrical electrodes are coaxially arranged and the pathway of current inside the switch is specially designed such that arc current sheet positioned between the coaxially arranged electrodes makes a self bouncing movement in an axial and/or circumferential direction. The self-bouncing arc switch according to the present invention makes it possible to maximize the working area of the electrodes, thereby spread arc energy effectively over the electrodes.
