Multi-phase switch with variable pole spacing

摘要

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.
