ABSTRACT:
A solid state switch connected across a pair of separable contacts for eliminating arcing across the contacts allows the contacts and the contact driver to be enclosed within an evacuated envelope. The vacuum environment allows the use of an inexpensive, highly conductive contact material, such as copper, without fear of chemical reaction.
