Vacuum switches are electromechanical devices that interrupt or establish electrical circuits by separating contacts within an evacuated envelope, eliminating arc-over and oxidation in high-voltage or high-current aerospace applications; they typically employ ceramic-to-metal hermetic sealing, copper-chromium or copper-bismuth contact alloys, and bellows-actuated mechanisms to maintain vacuum integrity across the required operational envelope.
