Abstract: A multi-pole switch characterized by spaced sets of stationary and movable contacts, mounting means for the movable contacts comprising a common contact operating shaft rotatable between open and closed positions of the contacts, the mounting means for each movable contact comprising a bracket operatively mounted on the operating shaft and having releasable means for retaining one contact at one position spaced from an adjacent contact, the bracket including means for releasably retaining one movable contact in one position laterally spaced from an adjacent contact, the mounting means also comprising a unitary insulating base mounted on the shaft and having spaced mounting stations for the movable contacts, and mounting means comprising interfitting releasable members for adjusting the lateral spacing between adjacent movable contacts.

Abstract: A circuit interrupter characterized by a stationary contact, a movable, elongated, tubular fuse in which one end of the fuse is swingably mounted about the other end in a predetermined path to open and close a circuit through the contact, and the other end of the fuse being pivotably seated between supporting conductors which are peripherally spaced around the fuse and one of which conductors is a leaf spring biased against said other end of the fuse.
