Abstract
An improved envelope for a vacuum-type current interrupter of the type having a pair of relatively movable electrodes. The envelope includes end portions which support the electrodes and an intermediate insulating portion which surrounds and is spaced from the electrodes. Baffles are provided along the interior surface of the insulating portion to break up continuous metallic vapor deposits on the interior of the envelope.
